11 and Aaron shall offer the Levites before the LORD for a wave offering, on the behalf of the children of Israel, that they may be to do the service of the LORD.
12 And the Levites shall lay their hands upon the heads of the bullocks: and offer thou the one for a sin offering, and the other for a burnt offering, unto the LORD, to make atonement for the Levites.
13 And thou shalt set the Levites before Aaron, and before his sons, and offer them for a wave 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 tent of meeting: and thou shalt cleanse them, and offer them for a wave offering.
16 For they are wholly given unto me from among the children of Israel; instead of all that openeth the womb, even the firstborn of all the children of Israel, have I taken them unto me.
17 For all the firstborn among the children of Israel are mine, both man and beast: on the day that I smote all the firstborn in the land of Egypt I sanctified them for myself.
