Exodus 13:11-13

Amplified Bible, Classic Edition

¹¹ And when the Lord brings you into the land of the Canaanites, as He promised and swore to you and your fathers, and shall give it to you,

¹² You shall set apart to the Lord all that first opens the womb. All the firstlings of your livestock that are males shall be the Lord’s.

¹³ Every firstborn of a donkey you shall redeem by [substituting for it] a lamb, or if you will not redeem it, then you shall break its neck; and every firstborn among your sons shall you redeem.
