Exodus 13:11-22

“And when the LORD takes you into the land of the Canaanites, the land he promised to give you and your ancestors, you must give him every firstborn male. Also every firstborn male animal must be given to the LORD. Buy back every firstborn donkey by offering a lamb. But if you don’t want to buy the donkey back, then break its neck. You must buy back from the LORD every firstborn of your sons. “From now on when your son asks you, ‘What does this mean?’ you will answer, ‘With his great power, the LORD brought us out from Egypt, the land where we were slaves. The king of Egypt was stubborn and refused to let us leave. But the LORD killed every firstborn male in Egypt, both human and animal. That is why I sacrifice every firstborn male animal to the LORD, and that is why I buy back each of my firstborn sons from the LORD.’ This feast is like a mark on your hand and a reminder on your forehead to help you remember that the LORD brought us out of Egypt with his great power.” When the king sent the people out of Egypt, God did not lead them on the road through the Philistine country, though that was the shortest way. God said, “If they have to fight, they might change their minds and go back to Egypt.” So God led them through the desert toward the Red Sea. The Israelites were dressed for fighting when they left the land of Egypt. Moses carried the bones of Joseph with him, because before Joseph died, he had made the Israelites promise to do this. He had said, “When God saves you, remember to carry my bones with you out of Egypt.” The Israelites left Succoth and camped at Etham, on the edge of the desert. The LORD showed them the way; during the day he went ahead of them in a pillar of cloud, and during the night he was in a pillar of fire to give them light. In this way they could travel during the day or night. The pillar of cloud was always with them during the day, and the pillar of fire was always with them at night.
