9. And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.
10. And thou shalt appoint Aaron and his sons, and they shall wait on their priest’s office: and the stranger that cometh nigh shall be put to death.
11. And the Lord spake unto Moses, saying,
12. And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the matrix among the children of Israel: therefore the Levites shall be mine;
13. Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the Lord.
14. And the Lord spake unto Moses in the wilderness of Sinai, saying,
15. Number the children of Levi after the house of their fathers, by their families: every male from a month old and upward shalt thou number them.
16. And Moses numbered them according to the word of the Lord, as he was commanded.
