Exodus 13:11-22

“Now it shall be when the LORD brings you into the land of the Canaanite, as He swore to you and your fathers, and gives it to you, you shall set apart and dedicate to the LORD all that first opens the womb. All the firstborn males of your livestock shall be the LORD’S. Every firstborn of a donkey you shall redeem by [substituting] a lamb [as a sacrifice for it], but if you do not [wish to] redeem it, then you shall break its neck; and every firstborn among your sons you shall redeem [that is, ‘buy back’ from God with a suitable sacrifice]. And it shall be when your son asks you in time to come, saying, ‘What does this mean?’ you shall say to him, ‘With a strong and powerful hand the LORD brought us out of Egypt, from the house of bondage and slavery. For it happened, when Pharaoh stubbornly refused to let us go, that the LORD struck every firstborn in the land of Egypt, both the firstborn of man and the firstborn of animal. Therefore, I sacrifice to the LORD all the males, the first [to be born] of every womb, but every firstborn of my sons I redeem.’ So it shall serve as a sign and a reminder on your [left] hand (arm) and as frontlets between your eyes, for by a strong and powerful hand the LORD brought us out of Egypt.” So it happened, when Pharaoh let the people go, God did not lead them by way of the land of the Philistines, even though it was nearer; for God said, “The people might change their minds when they see war [that is, that there will be war], and return to Egypt.” But God led the people around by the way of the wilderness toward the Red Sea; the sons of Israel went up in battle array (orderly ranks, marching formation) out of the land of Egypt. Moses took the bones of Joseph with him, for Joseph had solemnly ordered (placed under an oath) the Israelites, saying, “God will assuredly take care of you, and you must carry my bones away from here with you.” [Gen 50:25] They journeyed from Succoth [in Goshen] and camped at Etham on the edge of the wilderness. The [presence of the] LORD was going before them by day in a pillar (column) of cloud to lead them along the way, and in a pillar of fire by night to give them light, so that they could travel by day and by night. He did not withdraw the pillar of cloud by day, nor the pillar of fire by night, from going before the people.
