Exodus 13:14-16 The Voice (VOICE)
14 There will come a time when your children ask you, “What is this thing we are doing?” You will say, “With a strong hand the Eternal led us out of Egypt and freed us from lives of slavery. 15 When Pharaoh’s heart was as hard as stone, and he refused to release us, the Eternal killed all the firstborn in the land of Egypt (both humans and animals). That is why I sacrifice the firstborn male of all our livestock to Him, but then I redeem every firstborn son by sacrificing a substitute.”
16 These practices will be like a mark stamped on the back of your hand and a reminder written across your forehead, a constant reminder that the Eternal led us out of Egypt with a strong hand.
