1. And the Lord said to Aaron: "You, and your sons, and the house of your father with you, shall carry the iniquity of the Sanctuary. And you and your sons together shall bear the sins of your priesthood.
2. But take to yourselves also your brothers from the tribe of Levi, and the scepter of your father, and may they be prepared, and may they minister to you. Then you and your sons shall minister in the tabernacle of the testimony.
3. And the Levites shall stand watch by your precepts, and for all the works of the tabernacle; yet in such a manner that they shall not approach the vessels of the Sanctuary and of the altar, lest both they die, and you perish, at the same time.
4. But they may be with you, and they may watch over the care of the tabernacle and all its ceremonies. A foreigner shall not be mixed with you.
5. Watch over the care of the Sanctuary, and over the ministry of the altar, lest an indignation may rise over the sons of Israel.
6. I have given your brothers, the Levites, to you from the midst of the sons of Israel, and I have delivered them as a gift to the Lord, in order to serve in the ministries of his tabernacle.
7. But as for you and your sons: guard the priesthood. For all that pertains to the service of the altar and of what is beyond the veil shall be exercised by the priests. If any outsider will approach, he shall be killed."
8. And the Lord said to Aaron: "Behold, I have given you custody of my first-fruits. Everything that is sanctified by the sons of Israel I have delivered to you and your sons, for the office of the priesthood, by everlasting ordinances.
