For they, among the Israelites, are totally dedicated to me; I have taken them for myself in place of everyone that opens the womb, the firstborn of all the Israelites.
because every firstborn is mine. When I struck down all the firstborn in the land of Egypt, I consecrated to me every firstborn in Israel, human being and beast alike. They belong to me; I am the Lord. Census of the Levites.
Take the Levites in place of all the firstborn of the Israelites, and the Levites’ cattle in place of their cattle, that the Levites may belong to me. I am the Lord.
