82-508: Saadia is the first important rabbinic figure to write extensively in Judeo-Arabic . Known for his works on Hebrew linguistics , halakha , and Jewish philosophy , he was a practitioner of the philosophical school known as the " Jewish Kalam ". In this capacity, his philosophical work The Book of Beliefs and Opinions represents the first systematic attempt to integrate Jewish theology with components of ancient Greek philosophy . Saadia

164-541: A 19-year cycle, known as the Metonic cycle (See Leap months , below). The beginning of each Jewish lunar month is based on the appearance of the new moon . Although originally the new lunar crescent had to be observed and certified by witnesses (as is still done in Karaite Judaism and Islam ), nowadays Jewish months have generally fixed lengths which approximate the period between new moons. For these reasons,

246-674: A certain explanation is given in the Talmud , such as the Hebrew words בד בבד ‎ in Exo. 30:34 (explained in Taanit 7a as meaning "each spice pounded separately"), Saadia deviates from the rabbinic tradition in his Judeo-Arabic translation of the Pentateuch, in this case explaining its sense as "having them made of equal portions." In another apparent deviation from Talmudic tradition, where

328-460: A confrontation between the two strong-willed personalities, Exilarch David and Saadia. Nissim declared, however, that if David was determined to see Saadia in the position, then he would be ready to become the first of Saadia's followers. Under his leadership, the ancient academy of Sura founded by Abba Arikha entered upon a new period of brilliancy. This renaissance was cut short by a clash between Saadia and David, much as Nissim had predicted. In

410-556: A controversy arose concerning the Hebrew calendar , that threatened the entire Jewish community. Since Hillel II (around 359 CE), the calendar had been based on a series of rules (described more fully in Maimonides ' Code) rather than on observation of the lunar phases . One of these rules required the date of Rosh Hashanah to be postponed if the calculated lunar conjunction occurred at noon or later. Rabbi Aaron ben Meïr , head of

492-460: A dispute that had fallen out between him and the Exilarch. During Saadia's absence, his post was occupied by Joseph ben Jacob , the grandson of Natronai ben Hilai . At length, Saadia was reconciled with the Exilarch and returned to serve in his former position, although Joseph ben Jacob also remained serving in his capacity as Gaon. In 922, six years before Saadia was appointed Gaon of Babylonia,

574-482: A given month does not always begin on the same day as its astronomical conjunction. The mean period of the lunar month (precisely, the synodic month ) is very close to 29.5 days. Accordingly, the basic Hebrew calendar year is one of twelve lunar months alternating between 29 and 30 days: Thus, the year normally contains twelve months with a total of 354 days. In such a year, the month of Marcheshvan has 29 days and Kislev has 30 days. However, due to

656-451: A member of Sura Academy . Saadia, in Sefer ha-Galui , stresses his Jewish lineage, claiming to belong to the noble family of Shelah , son of Judah , and counting among his ancestors Hanina ben Dosa , the famous ascetic of the first century. Saadia expressed this claim by calling his son Dosa ; this son later served as gaon of Sura Academy from 1012–1018. Regarding Joseph, Saadia's father,

738-476: A period known as an iggul , or the Iggul of Rabbi Nahshon . This period is notable in that the precise details of the calendar almost always (but not always) repeat over this period. This occurs because the molad interval (the average length of a Hebrew month) is 29.530594 days, which over 247 years results in a total of 90215.965 days. This is almost exactly 90216 days – a whole number and multiple of 7 (equalling

820-544: A probate case, Saadia refused to sign a verdict of the exilarch, which he thought unjust, although the Gaon of Pumbedita had subscribed to it. When the son of the exilarch threatened Saadia with violence to secure his compliance and was roughly handled by Saadia's servant, open war broke out between the exilarch and the gaon. Each excommunicated the other, declaring that he deposed his opponent from office. David ben Zakkai appointed Joseph ben Jacob Gaon of Sura and Saadia conferred

902-648: A product of the Arabization of a large portion of Judaism, it served for centuries as a potent factor in the impregnation of the Jewish spirit with Arabic culture, so that, in this respect, it may take its place beside the Greek Bible-translation of antiquity and the German translation of the Pentateuch by Moses Mendelssohn. As a means of popular religious enlightenment, Saadia's translation presented

984-533: A remainder of 0 signifies Saturday. In Hebrew, these names may be abbreviated using the numerical value of the Hebrew letters, for example יום א׳ ( Day 1 , or Yom Rishon ( יום ראשון )): The names of the days of the week are modeled on the seven days mentioned in the Genesis creation account . For example, Genesis 1:8 "... And there was evening and there was morning, a second day" corresponds to Yom Sheni meaning "second day". (However, for days 1, 6, and 7

1066-535: A statement made by Abraham ibn Daud and doubtless derived from Saadia's son Dosa, Saadia himself died in Babylonia at Sura in 942, at the age of sixty, of "black gall" (melancholia), repeated illnesses having undermined his health. An anecdote is reported in Sefer Hasidim about Saadia ben Yosef "the sage," in which he ends a dispute between a servant who claims to be the heir of his deceased master and

1148-638: A statement of the ancient Jewish gaon Aaron ben Meïr has been preserved saying that he was compelled to leave Egypt and died in Jaffa , probably during Saadia's prolonged residence in the Holy Land . The usual nisba al-Fayyumi refers to Saadia's native place, the Fayyum , which is located in Middle Egypt ; in Hebrew, it is often given as Pitomi , derived from a contemporary identification of Fayum with

1230-624: Is 9:38 AM"). The Hebrew week ( שבוע , shavua ) is a cycle of seven days, mirroring the seven-day period of the Book of Genesis in which the world is created. The names for the days of the week are simply the day number within the week. The week begins with Day 1 ( Sunday ) and ends with Shabbat ( Saturday ). (More precisely, since days begin in the evening, weeks begin and end on Saturday evening. Day 1 lasts from Saturday evening to Sunday evening, while Shabbat lasts from Friday evening to Saturday evening.) Since some calculations use division,

1312-726: Is a bird that harbingers rain in the Levant (around October), for which reason the Talmud says: "When raḥam arrives, mercy ( raḥamīm ) comes into the world." He wrote both in Hebrew and in Arabic a work, now known only from a few fragments, entitled "Sefer ha-Galui" (Arabic title, "Kitab al-Ṭarid"), in which he emphasized with great but justifiable pride the services which he had rendered, especially in his opposition to heresy. The fourteen years which Saadia spent in Babylonia did not interrupt his literary activity. His principal philosophical work

1394-474: Is a leap year, find the remainder on dividing [(7 ×  n ) + 1] by 19. If the remainder is 6 or less it is a leap year; if it is 7 or more it is not. For example, the remainder on dividing [(7 × 5785) + 1] by 19 is 7, so the year 5785 is not a leap year. The remainder on dividing [(7 × 5786) + 1] by 19 is 14, so the year 5786 is not a leap year. This works because as there are seven leap years in nineteen years

1476-554: Is a seven-year release cycle. The placement of these cycles is debated. Historically, there is enough evidence to fix the sabbatical years in the Second Temple Period . But it may not match with the sabbatical cycle derived from the biblical period; and there is no consensus on whether or not the Jubilee year is the fiftieth year or the latter half of the forty ninth year. Every 247 years, or 13 cycles of 19 years, form

The cosmogony of Sefer Yetzirah is even omitted from the discussion of creation in his magnum opus "Kitab al-Amanat wal-I'tiḳadat." Concerning the supposed attribution of the book to the patriarch Abraham , he allows that the ideas it contains might be ancient. Nonetheless, he clearly considered the work worthy of deep study and echoes of Sefer Yetzirah's cosmogony do appear in "Kitab al-Amanat wal-I'tiḳadat" when Saadia discusses his theory of prophecy. Saadia translated

The very first molad, the molad tohu , fell on Sunday evening at 11:11:20 pm in the local time of Jerusalem , 6 October 3761 BCE ( Proleptic Julian calendar ) 20:50:23.1 UTC , or in Jewish terms Day 2, 5 hours, and 204 parts. The exact time of a molad in terms of days after midnight between 29 and 30 December 1899 (the form used by many spreadsheets for date and time)

1722-428: Is for calculating and announcing the molad . In another system, the daytime period is divided into 12 relative hours ( sha'ah z'manit , also sometimes called "halachic hours"). A relative hour is defined as 1 ⁄ 12 of the time from sunrise to sunset, or dawn to dusk, as per the two opinions in this regard. Therefore, an hour can be less than 60 minutes in winter, and more than 60 minutes in summer; similarly,

1804-723: Is of uncertain status. Thus (for example) observance of Shabbat begins before sundown on Friday and ends after nightfall on Saturday, to be sure that Shabbat is not violated no matter when the transition between days occurs. Instead of the International Date Line convention, there are varying opinions as to where the day changes. One opinion uses the antimeridian of Jerusalem (located at 144°47' W, passing through eastern Alaska ). Other opinions exist as well. (See International date line in Judaism .) Judaism uses multiple systems for dividing hours. In one system ,

1886-471: Is performed. To calculate the day on which Rosh Hashanah of a given year will fall, the expected molad (moment of lunar conjunction or new moon ) of Tishrei in that year is calculated. The molad is calculated by multiplying the number of months that will have elapsed since some (preceding) molad (whose weekday is known) by the mean length of a (synodic) lunar month, which is 29 days, 12 hours, and 793 parts (there are 1080 "parts" in an hour, so that one part

1968-432: Is the "real" Adar, and which is the added leap month. The Bible does not directly mention the addition of leap months (also known as "embolismic" or " intercalary " months). The insertion of the leap month is based on the requirement that Passover occur at the same time of year as the spring barley harvest ( aviv ). (Since 12 lunar months make up less than a solar year, the date of Passover would gradually move throughout

2050-462: Is the new year for kings and festivals. The 1st of Elul is the new year for the cattle tithe  ... The 1st of Tishri is the new year for years, of the Shmita and Jubilee years, for planting and for vegetables. The 1st of Shevat is the new year for trees—so the school of Shammai, but the school of Hillel say: On the 15th thereof . Two of these dates are especially prominent: For the dates of

2132-674: Is whether Saadia applied this principle in his other translations. Re'em (Hebrew: ראם , romanized:  rəʾēm ), as in Deuteronomy 33:17 , improperly translated as "unicorn" in some English translations, is a word that is now used in Modern Hebrew to represent the " oryx ." However, Saadia understood the same word to mean " rhinoceros " and writes there the Judeo-Arabic word for the creature ( Judeo-Arabic : אלכרכדאן , romanized:  al-karkadann ). He interprets

2214-456: The Gregorian calendar . Like other lunisolar calendars, the Hebrew calendar consists of months of 29 or 30 days which begin and end at approximately the time of the new moon. As 12 such months comprise a total of just 354 days, an extra lunar month is added every 2 or 3 years so that the long-term average year length closely approximates the actual length of the solar year . Originally,

2296-448: The Gregorian years (365.2425 days/year) make (0.0003 days/year, or one day in 3333 years). Besides the adding of leap months, the year length is sometimes adjusted by adding one day to the month of Marcheshvan, or removing one day from the month of Kislev. Because each calendar year begins with Rosh Hashanah , adjusting the year length is equivalent to moving the day of the next Rosh Hashanah. Several rules are used to determine when this

2378-459: The Jewish calendar , is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel . It determines the dates of Jewish holidays and other rituals, such as yahrzeits and the schedule of public Torah readings . In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside

2460-526: The Jews of Yemen has been exceptionally great, as many of Saadia's extant works were preserved by the community and used extensively by them. The basis for the Yemenite tiklāl is founded upon the prayer format edited originally by Saadia. The Yemenite Jewish community also adopted thirteen penitential verse written by Saadia for Yom Kippur , as well as the liturgical poems composed by him for Hoshana Rabbah ,

2542-617: The Palestinian Gaonate (then located in Ramla ), claimed a tradition according to which the cutoff point was 642/1080 of an hour (approximately 35 minutes) after noon. In that particular year, this change would result in a two-day schism with the major Jewish communities in Babylonia: according to Ben Meir the first day of Passover would be on a Sunday, while according to the generally accepted rule it would be on Tuesday.

2624-461: The Rosh Hashanah postponement rules , in some years Kislev may lose a day to have 29 days, or Marcheshvan may acquire an additional day to have 30 days. Normally the 12th month is named Adar . During leap years , the 12th and 13th months are named Adar I and Adar II (Hebrew: Adar Aleph and Adar Bet —"first Adar" and "second adar"). Sources disagree as to which of these months

2706-505: The Seder Olam Rabbah . Thus, adding 3760 before Rosh Hashanah or 3761 after to a Julian calendar year number starting from 1 CE will yield the Hebrew year. For earlier years there may be a discrepancy; see Missing years (Jewish calendar) . In Hebrew there are two common ways of writing the year number: with the thousands, called לפרט גדול ("major era"), and without the thousands, called לפרט קטן ("minor era"). Thus,

This system attempts to calculate

2870-550: The remainder . (Since there is no year 0, a remainder of 0 indicates that the year is year 19 of the cycle.) For example, the Jewish year 5785 divided by 19 results in a remainder of 9, indicating that it is year 9 of the Metonic cycle. The Jewish year used is the anno mundi year, in which the year of creation according to the Rabbinical Chronology (3761 BCE) is taken as year 1. Years 3, 6, 8, 11, 14, 17, and 19 of

In Saadia's translation and commentary on the Book of Psalms ( Kitāb al-Tasābiḥ ), he has done what no other medieval writer has done before him, bringing down a biblical exegesis and noting where the verse is to be read as a rhetorical question, and where the verse itself derides the question with good humor: הַר אֱלהִים הַר בָּשָׁן. הַר גַּבְנֻנִּים הַר בָּשָׁן לָמָּה תְּרַצְדוּן הָרִים גַּבְנֻנִּים הָהָר חָמַד אֱלהִים לְשִׁבְתּוֹ. אַף יי' יִשְׁכּן לָנֶצַח ‎ Is

3034-481: The 24-hour day is divided into fixed hours equal to 1 ⁄ 24 of a day, while each hour is divided into 1080 halakim (parts, singular: helek ). A part is 3 + 1 ⁄ 3 seconds ( 1 ⁄ 18 minute). The ultimate ancestor of the helek was a Babylonian time period called a barleycorn , equal to 1 ⁄ 72 of a Babylonian time degree (1° of celestial rotation). These measures are not generally used for everyday purposes; their best-known use

Relative hours are used for the calculation of prayer times ( zmanim ); for example, the Shema must be recited in the first three relative hours of the day. Neither system is commonly used in ordinary life; rather, the local civil clock is used. This is even the case for ritual times (e.g. "The latest time to recite Shema today

Saadia adopts in principle the method of the Sages that even the episodic-like parts of the Bible (e.g. story of Abraham and Sarah, the selling of Joseph, etc.) that do not contain commandments have a moral lesson to tell. In some instances, Saadia's biblical translations reflect his own rationale of difficult Hebrew words based on their lexical root, and he will, at times, reject

The beginning of this cycle is arbitrary. Its main use is for determining the time of Birkat Hachama . Because every 50 years is a Jubilee year, there is a jubilee ( yovel ) cycle. Because every seven years is a sabbatical year, there

According to rabbinic reckoning, this moment was not Creation , but about one year "before" Creation, with the new moon of its first month (Tishrei) called molad tohu (the mean new moon of chaos or nothing). It is about one year before the traditional Jewish date of Creation on 25 Elul AM 1, based upon

4100-407: The beginning of each month was determined based on physical observation of a new moon, while the decision of whether to add the leap month was based on observation of natural agriculture-related events in ancient Israel . Between the years 70 and 1178, these empirical criteria were gradually replaced with a set of mathematical rules. Month length now follows a fixed schedule which is adjusted based on

4264-491: The current year is written as ה'תשפ"ה ‎(5785) using the "major era" and תשפ"ה ‎(785) using the "minor era". Since the Jewish calendar has been fixed, leap months have been added according to the Metonic cycle of 19 years, of which 12 are common (non-leap) years of 12 months, and 7 are leap years of 13 months. This 19-year cycle is known in Hebrew as the Machzor Katan ("small cycle"). Because

So over 247 years, not only does the 19-year leap year cycle repeat itself, but the days of the week (and thus the days of Rosh Hashanah and the year length) typically repeat themselves.

In his commentary on the Sefer Yetzirah , Saadia sought to render lucid and intelligible

4510-408: The difference between the solar and lunar years increases by 7/19-month per year. When the difference goes above 18/19-month this signifies a leap year, and the difference is reduced by one month. The Hebrew calendar assumes that a month is uniformly of the length of an average synodic month , taken as exactly 29 13753 ⁄ 25920 days (about 29.530594 days, which is less than half a second from

4592-566: The earlier Targum for his own understanding. For example, in Psalm 16:4, Saadia retracts from the Targum (translated): "They will multiply their goddesses ( Hebrew : עַצְּבוֹתָם ); they have hastened after some other thing; I shall not pour out their libations of blood, neither shall I take-up their names upon my lips," writing instead: "They will multiply their revenues (Judeo-Arabic:אכסאבהם); they have hastened after some other thing," etc. Even where

Saadia was attacked by the exilarch and his chief adherent, the young but learned Aaron ibn Sargado (later Gaon of Pumbedita, 943-960), in Hebrew pamphlets. Fragments of these pamphlets show a hatred on the part of the exilarch and his partisans that did not shrink from scandal. Saadia did not fail to reply. Saadia's influence upon

The lengths of months in this period are fixed, meaning that the day of week of Passover dictates the day of week of the other Biblical holidays. However, the lengths of the months of Marcheshvan and Kislev can each vary by a day (due to the Rosh Hashanah postponement rules which are used to adjust

4920-641: The hill of God the hill of Bashan? A hunchback mountain is the hill of Bashan! (Meaning, it is unfit for God's Divine Presence). Why leap ye, ye hunchback mountains? That mountain wherein God desires to dwell (i.e. Mount Moriah in Jerusalem), even the Lord shall dwell [therein] forever more. Saadia's approach to rabbinic exegesis and midrashic literature was ambivalent. Although he adopted them in his liturgies, he did not recoil from denouncing them in his commentary on

The bone in the cup of the true heir absorbed the blood, while the servant's blood was not absorbed in the bone. Using this as genetic proof of the son's true inheritance, Saadia had the servant return the man's property to his son. Saadia Gaon

5084-552: The modern name differs slightly from the version in Genesis.) The seventh day, Shabbat , as its Hebrew name indicates, is a day of rest in Judaism. In Talmudic Hebrew, the word Shabbat ( שַׁבָּת ) can also mean "week", so that in ritual liturgy a phrase like "Yom Reviʻi beShabbat" means "the fourth day in the week". Jewish holidays can only fall on the weekdays shown in the following table: The period from 1 Adar (or Adar II , in leap years) to 29 Marcheshvan contains all of

The current Hebrew year, AM 5785, began at sunset on 2 October 2024 and will end at sunset on 22 September 2025. Based on the classic rabbinic interpretation of Genesis 1:5 ("There was evening and there was morning, one day"), a day in the rabbinic Hebrew calendar runs from sunset (the start of "the evening") to

5412-469: The oldest list of Hebrew grammarians, which is contained in the introduction to Abraham ibn Ezra 's "Moznayim," has not been challenged even by the latest historical investigations. Here, too, he was the first; his grammatical work, now lost, gave an inspiration to further studies, which attained their most brilliant and lasting results in Spain , and he created in part the categories and rules along whose lines

5494-500: The same year, he left Egypt and moved to Palestine . In 921, Saadia triumphed over Gaon Aaron ben Meïr over the latter's introduction of a new triennial cycle of Torah reading that also changed the dates of Passover and Rosh Hashanah . Later, one of Saadia's chief disputants was the Karaite by the name of Abu al-Surri ben Zuṭa, who is referred to by Abraham ibn Ezra , in his commentary on Exodus 21:24 and Leviticus 23:15 ). In

5576-775: The seventh day of Sukkot . Saadia's Judeo-Arabic translation of the Pentateuch, the Tafsir , was copied by the Yemenite Jews in nearly all their handwritten codices. They originally studied Saadia's major work of philosophy, Beliefs and Opinions , in its original Judeo-Arabic, although by the early 20th-century, only fragments survived. As much as Saadia's Judeo-Arabic translation of the Torah ( Tafsīr ) has brought relief and succour to Jews living in Arabic-speaking countries, his identification of places, fauna and flora, and

5658-403: The solar year exceed the lunar year? By approximately 11 days. Therefore, whenever this excess accumulates to about 30 days, or a little more or less, one month is added and the particular year is made to consist of 13 months, and this is the so-called embolismic (intercalated) year. For the year could not consist of twelve months plus so-and-so many days, since it is said: "throughout the months of

5740-534: The solar year if leap months were not occasionally added.) According to the rabbinic calculation, this requirement means that Passover (or at least most of Passover) should fall after the March equinox . Similarly, the holidays of Shavuot and Sukkot are presumed by the Torah to fall in specific agricultural seasons. Maimonides , discussing the calendrical rules in his Mishneh Torah (1178), notes: By how much does

5822-463: The stones of the priestly breastplate , has found him at variance with some scholars. Abraham ibn Ezra , in his commentary on the Torah, wrote scathing remarks on Saadia's commentary, saying: "He doesn't have an oral tradition […] perhaps he has a vision in a dream, while he has already erred with respect to certain places […]; therefore, we will not rely on his dreams." However, Saadia assures his readers elsewhere that when he rendered translations for

5904-551: The style of the Bible. He was likewise one of the founders of comparative philology, not only through his brief "Book of Seventy Words," already mentioned, but especially through his explanation of the Hebrew vocabulary by the Arabic, particularly in the case of the favorite translation of Biblical words by Arabic terms having the same sound. Saadia's works were the inspiration and basis for later Jewish writers, such as Berachyah in his encyclopedic philosophical work Sefer Hahibbur (The Book of Compilation). Saadia likewise identifies

5986-619: The twenty-odd unclean fowl mentioned in the Hebrew Bible , ( Leviticus 11:13–19; Deuteronomy 14:12–18) his translation was based on an oral tradition received by him. Saadia's method of conveying names for the fowls based on what he had received by way of an oral tradition prompted him to add in his defense: "Every detail about them, had one of them merely come unto us [for identification], we would not have been able to identify it for certain, much less recognize their related kinds." The question often asked by scholars now

6068-440: The week can be derived. The Hebrew calendar is a lunisolar calendar , meaning that months are based on lunar months , but years are based on solar years . The calendar year features twelve lunar months of 29 or 30 days, with an additional lunar month ("leap month") added periodically to synchronize the twelve lunar cycles with the longer solar year. These extra months are added in seven years (3, 6, 8, 11, 14, 17, and 19) out of

6150-456: The year 928, at the age of thirty-six (variant: forty-six), David ben Zakkai , the Exilarch or head of Babylonian Jewry, petitioned Saadia to assume the honorary title of gaon, where he was appointed that same year the Gaon of Sura Academy at Mata Mehasya , a position which he held for 14 years until his death. After only two years of teaching, Saadia recused himself from teaching because of

6232-536: The year length). As a result, the holidays falling after Marcheshvan (starting with Chanukah) can fall on multiple days for a given row of the table. A common mnemonic is " לא אד"ו ראש, ולא בד"ו פסח ", meaning: "Rosh HaShana cannot be on Sunday, Wednesday or Friday, and Passover cannot be on Monday, Wedesday or Friday" with each days' numerical equivalent, in gematria , is used, such that א' = 1 = Sunday, and so forth. From this rule, every other date can be calculated by adding weeks and days until that date's possible day of

6314-532: The year", which implies that we should count the year by months and not by days. The Hebrew calendar year conventionally begins on Rosh Hashanah , the first day of Tishrei . However, the Jewish calendar also defines several additional new years, used for different purposes. The use of multiple starting dates for a year is comparable to different starting dates for civil "calendar years", "tax or fiscal years ", " academic years ", and so on. The Mishnah (c. 200 CE) identifies four new-year dates: The 1st of Nisan

6396-418: Was a pioneer in the fields in which he toiled. The foremost object of his work was the Bible; his importance is due primarily to his establishment of a new school of Biblical exegesis characterized by a rational investigation of the contents of the Bible and a scientific knowledge of the language of the holy text. Saadia's Arabic translation of the Torah is of importance for the history of civilization; itself

6478-886: Was also very active in opposition to Karaite Judaism in defense of Rabbinic Judaism . Saadia was born in Dilāẓ in the Faiyum in Middle Egypt in 892. He immigrated to ancient Israel (in the Abbasid province of Bilad Al-Sham) in 915 at the age of 23, where he studied in Tiberias under the scholar Abu Kathir Yaḥya al-Katib (known as Eli ben Yehudah ha-Nazir in Hebrew), a Jewish mutakallim or theologian also mentioned by ibn Ḥazm . In 926, Saadia settled permanently in Lower Mesopotamia , known to Jews as " Babylonia ", where he became

6560-401: Was completed in 933; and four years later, through Ibn Sargado's father-in-law, Bishr ben Aaron, the two enemies were reconciled. Saadia was reinstated in his office; but he held it for only five more years. David b. Zakkai died before him (c. 940), being followed a few months later by the exilarch's son Judah, while David's young grandson was nobly protected by Saadia as by a father. According to

6642-538: Was developed the grammatical study of the Hebrew language. His dictionary, primitive and merely practical as it was, became the foundation of Hebrew lexicography; and the name "Agron" (literally, "collection"), which he chose and doubtless created, was long used as a designation for Hebrew lexicons, especially by the Karaites. The very categories of rhetoric, as they were found among the Arabs, were first applied by Saadia to

6724-627: Was in Aleppo , on his way from the East, when he learned of Ben Meïr's regulation of the Jewish calendar. Saadia addressed a warning to him, and in Mesopotamia, he placed his knowledge and pen at the disposal of the exilarch David ben Zakkai and the scholars of the academies, adding his letters to those sent by them to the communities of the Jewish diaspora (922). In Babylonia, he wrote his Sefer haMo'adim , or "Book of Festivals ," in which he refuted
