13 You can save the life of a firstborn donkey by sacrificing a lamb; if you don't, you must break the donkey's neck. You must save every firstborn son.
14 In the future your children will ask what this ceremony means. Explain it to them by saying, “The Lord used his mighty power to rescue us from slavery in Egypt.
15 The king stubbornly refused to set us free, so the Lord killed the firstborn male of every animal and the firstborn son of every Egyptian family. This is why we sacrifice to the Lord every firstborn male of every animal and save every firstborn son.”
16 This ceremony will serve the same purpose as a sign on your hand or on your forehead to tell how the Lord's mighty power rescued us from Egypt.
17 After the king had finally let the people go, the Lord did not lead them through Philistine territory, though that was the shortest way. God had said, “If they are attacked, they may decide to return to Egypt.”
18 So he led them around through the desert and towards the Red Sea.The Israelites left Egypt, prepared for battle.
19 Moses made them take along the bones of Joseph, whose dying words had been, “God will come to your rescue, and when he does, be sure to take along my bones.”
