Its redactor made use of Genesis Rabbah, Pesikta de-Rav Kahana, and the Jerusalem Talmud, in addition to other ancient sources.
Of the 37 homilies, eight (1, 3, 8, 11, 13, 20, 26, 30) are introduced with the formula "Patach R." or "The teacher has commenced"; eight (2, 4–7, 9, 10, 19), with "Hada hu dich'tiv" or "As it is written"; and 21 (12, 14–18, 21–25, 27–29, 31–37), with "Zeh she-amar ha-katuv" or "This is what the Holy Scriptures say."
[2] The length of Leviticus Rabbah is the same as that of the edition quoted by Nathan ben Jehiel in the Arukh, since he refers to passages from chapters 36 and 37 as "the end."
Like the lectures in the Pesikta, the homilies in Leviticus Rabbah begin with a larger or smaller number of poems on passages mostly taken from the Writings.
In some cases, long pieces, in others brief sentences only, have been adduced in connection with the Scriptural passages, seemingly in accordance with the material at the redactor's disposal.
