Numbers 3:13

for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt , I consecrated for my own all the firstborn in Israel , both of man and of beast . They shall be mine: I am the Lord .

for all the firstborn are mine. When I struck down all the firstborn in Egypt, I set apart for myself every firstborn in Israel, whether human or animal. They are to be mine. I am the Lord.”

Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast : mine shall they be: I am the Lord.
