11and Aaron shall offer the Levites before Yahweh for a wave-offering, on the behalf of the children of Israel, that it may be theirs to do the service of Yahweh.
12The Levites shall lay their hands on the heads of the bulls: and offer you the one for a sin-offering, and the other for a burnt offering, to Yahweh, to make atonement for the Levites.
13You shall set the Levites before Aaron, and before his sons, and offer them for a wave-offering to Yahweh.
14Thus shall you separate the Levites from among the children of Israel; and the Levites shall be mine.
15After that shall the Levites go in to do the service of the tent of meeting: and you shall cleanse them, and offer them for a wave-offering.
16For they are wholly given to me from among the children of Israel; instead of all who open the womb, even the firstborn of all the children of Israel, have I taken them to me.
17For all the firstborn among the children of Israel are mine, both man and animal: on the day that I struck all the firstborn in the land of Egypt I sanctified them for myself.
