Bamidbar 18:21-23

Orthodox Jewish Bible

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.

²³ But the Levi’im shall perform the Avodat Ohel Mo’ed, lest they shall nasa (bear) their avon; it shall be a chukkat olam throughout your derot, that among the Bnei Yisroel they have no nachalah.
