“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 the Lord.
You may redeem the firstborn of a donkey with a sheep, but if you do not redeem it, break its neck. You must redeem all the firstborn of your sons. No one is to appear before me empty-handed.
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.
