Numbers 18:2-4

New American Standard Bible

² But also bring your brothers with you, the tribe of Levi, the tribe of your father, so that they may ^(A)join you and serve you, while you and your sons with you are before the tent of the testimony. ³ And they shall perform duties for you and the duties of the whole tent, but ^(B)they shall not come near the furnishings of the sanctuary and ^(C)the altar, or both they and you will die. ⁴ They shall join you and perform the duties of the tent of meeting, for all the service of the tent; but ^[a]an unauthorized person shall not come near you.
