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 womb among the children of Israel; and the Levites shall be mine:
13. for all the firstborn are mine; 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 they shall be; I am the LORD.
14. And the LORD spake unto Moses in the wilderness of Sinai, saying,
15. Number the children of Levi by their fathers' houses, 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.
