8“On the seventh day you must explain to your children, ‘I am celebrating what the Lord did for me when I left Egypt.’ 9This annual festival will be a visible sign to you, like a mark branded on your hand or your forehead. Let it remind you always to recite this teaching of the Lord: ‘With a strong hand, the Lord rescued you from Egypt.’*10So observe the decree of this festival at the appointed time each year.

11“This is what you must do when the Lord fulfills the promise he swore to you and to your ancestors. When he gives you the land where the Canaanites now live, 12you must present all firstborn sons and firstborn male animals to the Lord, for they belong to him. 13A firstborn donkey may be bought back from the Lord by presenting a lamb or young goat in its place. But if you do not buy it back, you must break its neck. However, you must buy back every firstborn son.

14“And in the future, your children will ask you, ‘What does all this mean?’ Then you will tell them, ‘With the power of his mighty hand, the Lord brought us out of Egypt, the place of our slavery. 15Pharaoh stubbornly refused to let us go, so the Lord killed all the firstborn males throughout the land of Egypt, both people and animals. That is why I now sacrifice all the firstborn males to the Lord—except that the firstborn sons are always bought back.’ 16This ceremony will be like a mark branded on your hand or your forehead. It is a reminder that the power of the Lord’s mighty hand brought us out of Egypt.”

Israel’s Wilderness Detour

17When Pharaoh finally let the people go, God did not lead them along the main road that runs through Philistine territory, even though that was the shortest route to the Promised Land. God said, “If the people are faced with a battle, they might change their minds and return to Egypt.” 18So God led them in a roundabout way through the wilderness toward the Red Sea.* Thus the Israelites left Egypt like an army ready for battle.*

19Moses took the bones of Joseph with him, for Joseph had made the sons of Israel swear to do this. He said, “God will certainly come to help you. When he does, you must take my bones with you from this place.”

20The Israelites left Succoth and camped at Etham on the edge of the wilderness. 21The Lord went ahead of them. He guided them during the day with a pillar of cloud, and he provided light at night with a pillar of fire. This allowed them to travel by day or by night. 22And the Lord did not remove the pillar of cloud or pillar of fire from its place in front of the people.
