Bamidbar 18:6-8

Orthodox Jewish Bible

⁶ And I, hinei, I Myself have taken your brethren the Levi’im from among the Bnei Yisroel; to you they are given as a mattanah (gift) to Hashem, to do the Avodat Ohel Mo’ed [see Ep 4:11].

⁷ Therefore thou and thy Banim with thee shall be shomer over your Kehunah with everything of the Mizbe’ach, and within the Parochet; and ye shall do the Avodas service: I have given your Kehunah unto you as an Avodas Mattanah; and the zar (unauthorized one) that shall encroach shall be put to death.

⁸ And Hashem spoke unto Aharon, Hinei, I also have given thee the charge of Mine terumot of kol Kadoshei Bnei Yisroel; unto thee have I given them by reason of the moshchah (kohen’s allotted portion), and to thy Banim, as a chok olam.
