16. I have accepted them in place of the firstborn which open every womb in Israel.
17. For all the firstborn of the sons of Israel, as much from men as from beasts, are mine. From the day when I struck down all the firstborn in the land of Egypt, I have sanctified them to myself.
18. And I have taken the Levites in place of all the firstborn of the sons of Israel.
