Numbers 3:12–13

“Behold, I have taken the Levites from among the people of Israel instead of every firstborn who opens the womb among the people of Israel. The Levites shall be mine, 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.”

“I have taken the Levites from among the Israelites in place of the first male offspring of every Israelite woman. The Levites are mine, 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.”

“See, I have taken the Levites from the Israelites in place of every firstborn Israelite from the womb. The Levites belong to me, because every firstborn belongs to me. At the time I struck down every firstborn in the land of Egypt, I consecrated every firstborn in Israel to myself, both man and animal. They are mine; I am the Lord.”

“I myself receive the Levites from the midst of the Israelites in the place of all the firstborn of the offspring of the womb from the Israelites. The Levites will be mine because all the firstborn are mine; on the day of my killing all the firstborn in the land of Egypt, I consecrated for myself all the firstborn in Israel, both humankind and animal; they will be mine. I am Yahweh.”

And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the matrix among the children of Israel: therefore the Levites shall be mine; 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.
