12. And I, behold, I have taken the Levites from among the children of Israel instead of all the first-born that openeth the womb among the children of Israel; and the Levites shall be mine:
13. for all the first-born are mine; on the day that I smote all the first-born in the land of Egypt I hallowed unto me all the first-born in Israel, both man and beast; mine they shall be: I am Jehovah.
14. And Jehovah 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 Jehovah, as he was commanded.
17. And these were the sons of Levi by their names: Gershon, and Kohath, and Merari.
18. And these are the names of the sons of Gershon by their families: Libni and Shimei.
