Numbers 18:2-6

LITV(i) 2 and also your brothers, the tribe of Levi, the tribe of your father, you shall bring near with you, that they may be joined to you and may minister to you, you and your sons in your being before the tabernacle of the testimony. 3 And they shall keep your charge and the charge of all the tabernacle; only, they shall not go near to the vessels of the sanctuary and to the altar. And they shall not die either they or you. 4 And they shall be joined to you, and shall keep the charge of the tabernacle of the congregation, for all the service of the tabernacle, and a stranger shall not go near to you. 5 And you shall keep the charge of the sanctuary, and the charge of the altar, and there shall be no more wrath against the sons of Israel. 6 And I, behold, I have taken your brothers the Levites from the midst of the sons of Israel; as a gift they are given to you by Jehovah, to do the service of the tabernacle of the congregation.
