Numbers 18:1-8

1Then the Lord said to Aaron: “You, your sons, and your relatives from the tribe of Levi will be held responsible for any offenses related to the sanctuary. But you and your sons alone will be held responsible for violations connected with the priesthood.

2“Bring your relatives of the tribe of Levi—your ancestral tribe—to assist you and your sons as you perform the sacred duties in front of the Tabernacle of the Covenant.

3But as the Levites go about all their assigned duties at the Tabernacle, they must be careful not to go near any of the sacred objects or the altar. If they do, both you and they will die.

4The Levites must join you in fulfilling their responsibilities for the care and maintenance of the Tabernacle, but no unauthorized person may assist you.

5“You yourselves must perform the sacred duties inside the sanctuary and at the altar. If you follow these instructions, the Lord’s anger will never again blaze against the people of Israel.

6I myself have chosen your fellow Levites from among the Israelites to be your special assistants. They are a gift to you, dedicated to the Lord for service in the Tabernacle.

7But you and your sons, the priests, must personally handle all the priestly rituals associated with the altar and with everything behind the inner curtain. I am giving you the priesthood as your special privilege of service. Any unauthorized person who comes too near the sanctuary will be put to death.”

8The Lord gave these further instructions to Aaron: “I myself have put you in charge of all the holy offerings that are brought to me by the people of Israel. I have given all these consecrated offerings to you and your sons as your permanent share.
