¹¹ And Aaron shall offer the Levites before the Lord for an offering of the children of Israel, that they may execute the service of the Lord.

¹² And the Levites shall lay their hands upon the heads of the bullocks: and thou shalt offer the one for a sin offering, and the other for a burnt offering, unto the Lord, to make an atonement for the Levites.

¹³ And thou shalt set the Levites before Aaron, and before his sons, and offer them for an offering unto the Lord.

¹⁴ Thus shalt thou separate the Levites from among the children of Israel: and the Levites shall be mine.

¹⁵ And after that shall the Levites go in to do the service of the tabernacle of the congregation: and thou shalt cleanse them, and offer them for an offering.

¹⁶ For they are wholly given unto me from among the children of Israel; instead of such as open every womb, even instead of the firstborn of all the children of Israel, have I taken them unto me.

¹⁷ For all the firstborn of the children of Israel are mine, both man and beast: on the day that I smote every firstborn in the land of Egypt I sanctified them for myself.

¹⁸ And I have taken the Levites for all the firstborn of the children of Israel.
