⁶ “Take the Levites from among the Israelites and cleanse them. ⁷ Thus you shall do to them, to cleanse them: sprinkle the water of purification on them; have them shave their whole body with a razor and wash their clothes and so cleanse themselves.^{(A) 8} Then let them take a young bull and its grain offering of choice flour mixed with oil, and you shall take another young bull for a purification offering.^{(B) 9} You shall bring the Levites before the tent of meeting and assemble the whole congregation of the Israelites.^{(C) 10} When you bring the Levites before the Lord, the Israelites shall lay their hands on the Levites, ¹¹ and Aaron shall present the Levites before the Lord as an elevation offering from the Israelites, that they may do the service of the Lord. ¹² The Levites shall lay their hands on the heads of the bulls, and he shall offer the one for a purification offering and the other for a burnt offering to the Lord, to make atonement for the Levites.^{(D) 13} Then you shall have the Levites stand before Aaron and his sons, and you shall present them as an elevation offering to the Lord.

¹⁴ “Thus you shall separate the Levites from among the other Israelites, and the Levites shall be mine.^{(E) 15} Thereafter the Levites may go in to do service at the tent of meeting, once you have cleansed them and presented them as an elevation offering.^{(F) 16} For they are unreservedly given to me from among the Israelites; I have taken them for myself, in place of all that open the womb, the firstborn of all the Israelites.^{(G) 17} For all the firstborn among the Israelites are mine, both human and animal. On the day that I struck down all the firstborn in the land of Egypt I consecrated them for myself, ¹⁸ but I have taken the Levites in place of all the firstborn among the Israelites. ¹⁹ Moreover, I have given the Levites as a gift to Aaron and his sons from among the Israelites, to do the service for the Israelites at the tent of meeting and to make atonement for the Israelites, in order that there may be no plague among the Israelites for coming too close to the sanctuary.”^(H)

²⁰ Moses and Aaron and the whole congregation of the Israelites did with the Levites accordingly; the Israelites did with the Levites just as the Lord had commanded Moses concerning them. ²¹ The Levites purified themselves from sin and washed their clothes; then Aaron presented them as an elevation offering before the Lord, and Aaron made atonement for them to cleanse them.^{(I) 22} Thereafter the Levites went in to do their service in the tent of meeting in attendance on Aaron and his sons. As the Lord had commanded Moses concerning the Levites, so they did with them.

Responsibility of Priests and Levites

18 The Lord said to Aaron, “You and your sons and your ancestral house with you shall bear responsibility for offenses connected with the sanctuary, while you and your sons alone shall bear responsibility for offenses connected with the priesthood.^{(A) 2} So bring with you also your brothers of the tribe of Levi, your ancestral tribe, in order that they may be joined to you and serve you while you and your sons with you are in front of the tent of the covenant.^{(B) 3} They shall perform duties for you and for the whole tent. But they must not approach either the utensils of the sanctuary or the altar, or else both they and you will die.^{(C) 4} They are attached to you in order to perform the duties of the tent of meeting, for all the service of the tent; no outsider shall approach you.^{(D) 5} You yourselves shall perform the duties of the sanctuary and the duties of the altar, so that wrath may never again come upon the Israelites.^{(E) 6} It is I who now take your brother Levites from among the Israelites; they are now yours as a gift, dedicated to the Lord, to perform the service of the tent of meeting.^{(F) 7} But you and your sons with you shall diligently perform your priestly duties in all that concerns the altar and the area behind the curtain. I give your priesthood as a gift;^[a] any outsider who approaches shall be put to death.”^(G)
