¹⁴ In the future, when your son asks what this observance means, you will answer him, ‘By using great power the Lord brought us out of Egypt, the place where we were slaves. ¹⁵ When the king of Egypt was stubborn and refused to let us go, the Lord killed every first-born male in the land of Egypt, both human and animal. That is why we sacrifice every first-born male animal to the Lord, but buy back our first-born sons. ¹⁶ This observance will be a reminder, like something tied on our hands or on our foreheads; it will remind us that the Lord brought us out of Egypt by his great power.’”
