13 because all the firstborn are Mine. On the day that I struck all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, both man and beast. They shall be Mine: I am the Lord.”
14 Then the Lord spoke to Moses in the Wilderness of Sinai, saying:
15 “Number the children of Levi by their fathers’ houses, by their families; you shall number every male from a month old and above.”
16 So Moses numbered them according to the word of the Lord, as he was commanded.
17 These were the sons of Levi by their names: Gershon, 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, Izehar, Hebron, and Uzziel.
