Every firstborn donkey you are to redeem with a lamb, or if you do not redeem it, you must break its neck. And every firstborn son among your children you are to redeem.
In context
11When Yahweh brings you into the land of the Canaanites, as he swore to you and to your fathers, and gives it to you, 12you are to set apart to Yahweh whatever first opens the womb. Every firstborn male of your livestock belongs to Yahweh. 13Every firstborn donkey you are to redeem with a lamb, or if you do not redeem it, you must break its neck. And every firstborn son among your children you are to redeem. 14And when your son asks you in the future, ‘What is this?’ you are to tell him, ‘With a mighty hand Yahweh brought us out of Egypt, out of the house of slavery. 15When Pharaoh stubbornly refused to let us go, Yahweh killed every firstborn in the land of Egypt, both the firstborn of people and the firstborn of animals. That is why I sacrifice to Yahweh every male that first opens the womb, and why I redeem every firstborn of my sons.’
