13. Because all the first-born are mine; for on the day that I smote all the first-born in the land of Egypt, I hallowed to me all the first-born in Israel, both man and beast: mine they shall be: I am the LORD.
14. And the LORD spoke to 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.
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.
19. And the sons of Kohath by their families; Amram, and Izehar, Hebron, and Uzziel.
