Exodus 13:13-15

Holman Christian Standard Bible

¹³ You must redeem every firstborn of a donkey with a flock animal, but if you do not redeem it, break its neck. However, you must redeem every firstborn among your sons.^(A)

¹⁴ “In the future, when your son^(B) asks you, ‘What does this mean?’ say to him, ‘By the strength of His hand the Lord brought us out of Egypt, out of the place of slavery. ¹⁵ When Pharaoh stubbornly refused to let us go, the Lord killed every firstborn male in the land of Egypt, from the firstborn of man to the firstborn of livestock. That is why I sacrifice to the Lord all the firstborn of the womb that are males, but I redeem all the firstborn of my sons.’
