Every firstborn donkey can be bought back. You can offer a lamb and keep the donkey. If you don’t want to buy back the donkey like this, then you must break its neck to kill it. But every firstborn baby boy must be bought back from the Lord.
In Egypt, Pharaoh was stubborn and refused to let us leave. So the Lord killed every firstborn in all the land. (The Lord killed the firstborn males—animal and human.) That is why I give every firstborn male animal to the Lord, and that is why I buy back each of my firstborn sons from him.’
