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.
17. And these were the sons of Levi by their names; Gershon, and Kohath, and Merari.
