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.
