Numbers 8:16-18

New American Standard Bible

¹⁶ for they are ^(A)exclusively given to Me from among the sons of Israel. I have taken them for Myself ^(B)instead of the firstborn of every womb, the firstborn of all the sons of Israel. ¹⁷ For ^(C)every firstborn among the sons of Israel is Mine, among the people and among the animals; on the day that I fatally struck all the firstborn in the land of Egypt, I sanctified them for Myself. ¹⁸ But I have taken the Levites instead of every firstborn among the sons of Israel.
