Numbers 18:1-4

¹Yahweh said to Aaron, “You, your sons, and your ancestor's clan will be responsible for all sins committed against the sanctuary. But only you and your sons with you will be responsible for all sins committed by anyone in the priesthood.

²As for your fellow members of the tribe of Levi, your ancestors' tribe, you must bring them with you so they may join you and help you when you and your sons serve in front of the tent of the covenant decrees.

³They must serve you and the whole tent. However, they must not come near to anything in the holy place or connected with the altar, or they and also you will die.

⁴They must join you and take care of the tent of meeting, for all the work connected with the tent. A foreigner must not come near you.
