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 perform 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 to me from among the children of Israel; instead of such as open every womb, even instead of the first-born of all the children of Israel, have I taken them to me.
17. For all the first born of the children of Israel are mine, both man and beast: on the day that I smote every first-born in the land of Egypt I sanctified them for myself.
18. And I have taken the Levites for all the first-born of the children of Israel.
