Leviticus Rabbah, Vayikrah Rabbah, or Wayiqra Rabbah is a homiletic midrash to the Biblical book of Leviticus (Vayikrah in Hebrew). It is referred to by Nathan ben Jehiel (c. 1035–1106) in his Arukh as well as by Rashi (1040–1105).[1] According to Leopold Zunz, Hai Gaon (939-1038) and Nissim knew and made use of it. Zunz dates it to the middle of the 7th century, but The Encyclopaedia Judaica and Jacob Neusner date it to the 5th century. It originated in the Land of Israel, and is composed largely of older works. Its redactor made use of Genesis Rabbah, Pesikta de-Rav Kahana, and the Jerusalem Talmud, in addition to other ancient sources. The redactor appears to have referred also to the Babylonian Talmud, using several expressions in the sense in which only that work employs them.
