Exodus 13:11-16 Holman Christian Standard Bible (HCSB)
11 “When the Lord brings you into the land of the Canaanites, as He swore to you and your fathers, and gives it to you, 12 you are to present to the Lord every firstborn male of the womb. All firstborn offspring of the livestock you own that are males will be the Lord’s. 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.
14 “In the future, when your son 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.’ 16 So let it be a sign on your hand and a symbol[a] on your forehead, for the Lord brought us out of Egypt by the strength of His hand.”
