Bamidbar 18:20-22

Orthodox Jewish Bible

²⁰ And Hashem spoke unto Aharon, Thou shalt have no nachalah in their land, neither shalt thou have any chelek among them; I am thy chelek and thine nachalah among the Bnei Yisroel.

²¹ And, hinei, I have given the Bnei Levi all the ma’aser (tithe) in Yisroel for a nachalah, for their Avodah which they serve, even the Avodat Ohel Mo’ed.

²² Neither must the Bnei Yisroel henceforth come near the Ohel Mo’ed, lest they bear chet, and die.
