192-541: Is a midrash on the names of the letters of the Hebrew alphabet . Two versions or portions of this midrash are known to exist. Version A, which is considered by Adolf Jellinek to be the older form, and by Bloch  [ de ] to be of a much more recent origin, introduces the various anthropomorphized letters of the Hebrew alphabet that God engraved from His crown with a pen of fire contending with each other for

216-501: Is simply a compilation of aggadic passages taken at random from these and other kabbalistic and midrashic works without any other connection than the external order of the letters of the alphabet, but also based on Shabbat 104a. Jellinek has shown the time of its composition to be comparatively modern, as is evidenced by the Arabic form of the letters and other indications of Arabic life. It has, however, become especially valuable as

240-473: Is the chief of all letters, denoting the oneness of God, and that it shall have its place at the beginning of the Sinaitic revelation . This competition is followed by an aggadic explanation of the form of the various letters and by interpretations of the different compositions of the alphabet: ATav BSh , AHetSam BTetAyin, and AL BM. Version B is a compilation of allegoric and mystic Aggadahs suggested by

264-789: The cultural history of the German Jews in the Middle Ages. According to Gross, Isaac's chief importance rests upon the fact that he introduced among the Jewish communities in Slavic lands the study of the Talmud from France and the west of Germany. Isaac was of a mild and peace-loving character and it was for this reason, perhaps, that he did not participate in the struggle against the study of secular sciences, though an incorrect ritual decision would rouse him to indignant energy.

On the other hand, version B (which H. Grätz considered as being the original, and the works "Enoch" and " Shiur Komah " as sections of it) shows no inner unity of plan, but

312-716: The Karaite, in the 13th century. As to Rabbi Akiva 's authorship, this is claimed by the writers of both versions, who begin their compositions with the words, "R. Akiva has said." The justification for this pseudonymous title was found in the fact that, according to the Talmud , Moses was told on Sinai that the ornamental crown of each letter of the Torah would be made the object of halakhic interpretation by Rabbi Akiva , and that according to Genesis Rabbah 1, he and Rabbi Eliezer as youths already knew how to derive higher meaning from

336-536: The author carried on with Talmudic scholars of Italy , France, and Austria . Older collections of halachic decisions which the author had gathered together during his lifetime seem also to be embodied in the work. Isaac explains unknown words in Bohemian (i. e.

360-582: The depository of these very kabbalistic works, which nearly fell into oblivion due to the grossly anthropomorphic views of the Godhead expressed therein, which offended to the more enlightened minds of a later age. For this reason, the Alphabet of Rabbi Akiva was severely attacked and ridiculed by Solomon ben Jeroham , the Karaite , in the early 10th century. Version A was likewise known to Judah Hadassi ,

384-545: The double form of the letters. In fact, there exists a third version, called Midrash de-Rabbi Akiva al ha-Taggin ve-Tziyunim , a Midrash of Rabbi Akiva treating on the ornamentations of the letters of the alphabet with a view to finding in each of them some symbolic expression of God, Creation, the Torah, Israel, and the Jewish rites and ceremonies.

It is based upon Genesis Rabbah 1 and Shir haShirim Rabbah on 5:11, according to which Aleph (א) complained before God that Bet (ב) was preferred to it, but was assured that the Torah of Sinai, the object of creation, would begin with Aleph (אנכי = Anochi = I am); it, however, varies from the Midrash Rabbot . The letters, beginning with

480-513: The last, Tav, and ending with Bet, all assert their claim to be the first letter in the Torah: So all the remaining letters complain - each having some claim, each immediately refuted - until Bet (ב), the initial letter of berakhah (ברכה = "blessing" and "praise"), is chosen.
