14 Then the Lord spoke to Moses in the wilderness of Sinai, saying,
15 "Number the sons of Levi by their fathers' households, by their families; every male from a month old and upward you shall number."
16 So Moses numbered them according to the word of the Lord, just as he had been commanded.
17 These then are the sons of Levi by their names: Gershon and Kohath and Merari.
18 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 Izhar, Hebron and Uzziel;
20 and the sons of Merari by their families: Mahli and Mushi. These are the families of the Levites according to their fathers' households.
