Exodus 13:11-22

“Now when the LORD brings you to the land of the Canaanite, as He swore to you and to your fathers, and gives it to you, you shall devote to the LORD the first offspring of every womb, and the first offspring of every beast that you own; the males belong to the LORD. But every first offspring of a donkey you shall redeem with a lamb, but if you do not redeem it, then you shall break its neck; and every firstborn of man among your sons you shall redeem. And it shall be when your son asks you in time to come, saying, ‘What is this?’ then you shall say to him, ‘With a powerful hand the LORD brought us out of Egypt, from the house of slavery. It came about, when Pharaoh was stubborn about letting us go, that the LORD killed every firstborn in the land of Egypt, both the firstborn of man and the firstborn of beast. Therefore, I sacrifice to the LORD the males, the first offspring of every womb, but every firstborn of my sons I redeem.’ So it shall serve as a sign on your hand and as phylacteries on your forehead, for with a powerful hand the LORD brought us out of Egypt.” Now when Pharaoh had let the people go, God did not lead them by the way of the land of the Philistines, even though it was near; for God said, “The people might change their minds when they see war, and return to Egypt.” Hence God led the people around by the way of the wilderness to the Red Sea; and the sons of Israel went up in martial array from the land of Egypt. Moses took the bones of Joseph with him, for he had made the sons of Israel solemnly swear, saying, “God will surely take care of you, and you shall carry my bones from here with you.” Then they set out from Succoth and camped in Etham on the edge of the wilderness. The LORD was going before them in a pillar of cloud by day to lead them on the way, and in a pillar of fire by night to give them light, that they might travel by day and by night. He did not take away the pillar of cloud by day, nor the pillar of fire by night, from before the people.
