13 The Lord spoke to Moses: ² “Consecrate every firstborn male^(A) to me, the firstborn from every womb among the Israelites, both man and domestic animal; it is mine.”

²⁶ And Moses stood at the camp’s entrance and said, “Whoever is for the Lord, come to me.” And all the Levites gathered around him. ²⁷ He told them, “This is what the Lord, the God of Israel, says, ‘Every man fasten his sword to his side; go back and forth through the camp from entrance to entrance, and each of you kill his brother, his friend, and his neighbor.’”^{(A) 28} The Levites did as Moses commanded, and about three thousand men fell dead that day among the people. ²⁹ Afterward Moses said, “Today you have been dedicated^[a] to the Lord, since each man went against his son and his brother. Therefore you have brought a blessing on yourselves today.”^(B)

⁶ “Bring the tribe of Levi near and present them to the priest Aaron to assist him.

¹² “See, I have taken the Levites from the Israelites in place of every firstborn Israelite from the womb.^(A) The Levites belong to me, ¹³ because every firstborn belongs to me. At the time I struck down every firstborn in the land of Egypt,^(B) I consecrated every firstborn in Israel to myself, both man and animal. They are mine; I am the Lord.”^(C)

Redemption of the Firstborn

⁴⁰ The Lord told Moses, “Register every firstborn male of the Israelites^(A) one month old or more, and list their names. ⁴¹ You are to take the Levites for me—I am the Lord—in place of every firstborn among the Israelites, and the Levites’ cattle in place of every firstborn among the Israelites’ cattle.” ⁴² So Moses registered every firstborn among the Israelites, as the Lord commanded him. ⁴³ The total number of the firstborn males one month old or more listed by name was 22,273.
