Numbers 18:1 In-Context

1 The Lord said to Aaron, "You, your sons, and the Levites must suffer the consequences of any guilt connected with serving in the Tent of my presence; but only you and your sons will suffer the consequences of service in the priesthood.
2 Bring in your relatives, the tribe of Levi, to work with you and help you while you and your sons are serving at the Tent.
3 They are to fulfill their duties to you and their responsibilities for the Tent, but they must not have any contact with sacred objects in the Holy Place or with the altar. If they do, both they and you will be put to death.
4 They are to work with you and fulfill their responsibilities for all the service in the Tent, but no unqualified person may work with you.
5 You and your sons alone must fulfill the responsibilities for the Holy Place and the altar, so that my anger will not again break out against the people of Israel.
