Exodus 13:11-13

New Century Version

¹¹ “And when the Lord takes you into the land of the Canaanites, the land he promised to give you and your ancestors, ¹² you must give him every firstborn male. Also every firstborn male animal must be given to the Lord. ¹³ Buy back every firstborn donkey by offering a lamb. But if you don’t want to buy the donkey back, then break its neck. You must buy back from the Lord every firstborn of your sons.
