You are to take the Levites for Me — I am Yahweh — in place of every firstborn among the Israelites, and the Levites’ cattle in place of every firstborn among the Israelites’ cattle.”
The firstborn of every living thing, man or animal, presented to the Lord belongs to you. But you must certainly redeem the firstborn of man, and redeem the firstborn of an unclean animal.
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 Yahweh.”
“Take the Levites in place of every firstborn among the Israelites, and the Levites’ cattle in place of their cattle. The Levites belong to Me; I am Yahweh.
For they have been exclusively assigned to Me from the Israelites. I have taken them for Myself in place of all who come first from the womb, every Israelite firstborn.
