Numbers 8:17

For all the firstborn among the people of Israel are mine, both of man and of beast . On the day that I struck down all the firstborn in the land of Egypt I consecrated them for myself,

Every firstborn male in Israel, whether human or animal, is mine. When I struck down all the firstborn in Egypt, I set them apart for myself.

For all the firstborn of the children of Israel are mine, both man and beast : on the day that I smote every firstborn in the land of Egypt I sanctified them for myself.
