17 wFor all the firstborn among the people of Israel are mine, both of man and of beast. On the day that I struck down all the firstborn in the land of Egypt I consecrated them for myself,
12 dyou shall set apart to the Lord all that first opens the womb. All the firstborn of your animals that are males shall be the Lord's.
15 For when Pharaoh stubbornly refused to let us go, the jLord killed all the firstborn in the land of Egypt, both the firstborn of man and the firstborn of animals. Therefore I sacrifice to the Lord all the males that first open the womb, but kall the firstborn of my sons I redeem.’
