13. And thou shalt set the Levites before Aaron, and before his sons, and offer them as a wave-offering to Jehovah.
14. And thou shalt separate the Levites from among the children of Israel, that the Levites may be mine.
15. And afterwards shall the Levites come in to do the service of the tent of meeting. And thou shalt cleanse them, and offer them as a wave-offering.
16. For they are wholly given unto me from among the children of Israel; instead of every one that breaketh open the womb, instead of every firstborn among the children of Israel, have I taken them unto me.
17. For all the firstborn among the children of Israel are mine, both of man and beast; on the day that I smote every firstborn in the land of Egypt, I hallowed them to myself.
18. And I have taken the Levites instead of all the firstborn among the children of Israel.
