14 “In the future, your children will ask why you do this. They will say, ‘What does all this mean?’ And you will answer, ‘The Lord used his great power to save us from Egypt. We were slaves in that place, but he led us out and brought us here.
15 In Egypt, Pharaoh was stubborn and refused to let us leave. So the Lord killed every firstborn in all the land. (The Lord killed the firstborn males—animal and human.) That is why I give every firstborn male animal to the Lord, and that is why I buy back each of my firstborn sons from him.’
16 This is like a string tied on your hand, like a sign in front of your eyes. It helps you remember that the Lord brought us out of Egypt with his great power.”
17 Pharaoh made the people leave Egypt. God did not let the people take the road leading to the land of the Philistines. That road by the Mediterranean Sea is the shortest way, but God said, “If the people go that way they will have to fight. Then they might change their minds and go back to Egypt.”
18 So God led them another way through the desert by the Red Sea. The Israelites were dressed for war when they left Egypt.
19 Moses carried the bones of Joseph with him. Before Joseph died, he made the Israelites promise to do this for him. He said, “When God saves you, remember to carry my bones with you out of Egypt.”
20 The Israelites left Succoth and camped at Etham. Etham was near the desert.
