Bereshith Rabba is the title of a midrash or commentary on Genesis, composed in Palestine in the 6th century. The last five chapters, commencing with the section וִיחַי (Ge 47:12 sq.), hence also called Vaichi Rabba, are more modern, probably of the 11th century. A careful examination of this midrash proves that its author made use of Bar-Sira or Ben-Sira, Mishna, Tosephta, Sifre, Sifri, Mechilta, Seder Olam, the Onkelos Version and Jonathan Targum, etc. This midrash is now accessible to students in the German translation published by. A. W. Vimsche, in his Bibliotheca Rabbinica (Leips. 1880). Besides Zunz, Goftesdienstliche Vortrdye, p.
