13For all the first sons are mine; on the day when I put to death all the first sons in the land of Egypt, I took for myself every first male birth of man and beast. They are mine; I am the Lord.
14And the Lord said to Moses in the waste land of Sinai,
15Let all the children of Levi be numbered by their families and their fathers' houses; let every male of a month old and over be numbered.
16So Moses did as the Lord said, numbering them as he had been ordered.
17These were the sons of Levi by name: Gershon and Kohath and Merari.
18And these are the names of the sons of Gershon, by their families: Libni and Shimei.
19And the sons of Kohath, by their families: Amram and Izhar and Hebron and Uzziel.
