English Standard Version

Chapter 3

13 for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt, I consecrated for my own all the firstborn in Israel, both of man and of beast. They shall be mine: I am the LORD.” 14 And the LORD spoke to Moses in the wilderness of Sinai, saying, 15 “List the sons of Levi, by fathers’ houses and by clans; every male from a month old and upward you shall list.”
