Exodus 13:11-13

Complete Jewish Bible

¹¹ When Adonai brings you into the land of the Kena‘ani, as he swore to you and your ancestors, and gives it to you, ¹² you are to set apart for Adonai everything that is first from the womb. Every firstborn male animal will belong to Adonai. ¹³ Every firstborn from a donkey, you are to redeem with a lamb; but if you choose not to redeem it, you must break its neck. But from people, you are to redeem every firstborn son.
