11 "And it shall be, when the Lord brings you into the land of the Canaanites, as He swore to you and your fathers, and gives it to you, 12 that you shall set apart to the Lord all that open the womb, that is, every firstborn that comes from an animal which you have; the males shall be the Lord's. 13 But every firstborn of a donkey you shall redeem with a lamb; and if you will not redeem it, then you shall break its neck. And all the firstborn of man among your sons you shall redeem. 14 So it shall be, when your son asks you in time to come, saying, 'What is this?' that you shall say to him, 'By strength of hand the Lord brought us out of Egypt, out of the house of bondage. 15 And it came to pass, when Pharaoh was stubborn about letting us go, that the Lord killed all the firstborn in the land of Egypt, both the firstborn of man and the firstborn of beast. Therefore I sacrifice to the Lord all males that open the womb, but all the firstborn of my sons I redeem.' 16 It shall be as a sign on your hand and as frontlets between your eyes, for by strength of hand the Lord brought us out of Egypt."

The Pillar of Cloud and the Pillar of Fire

17 Then it came to pass, when Pharaoh had let the people go, that God did not lead them by way of the land of the Philistines, although that was near; for God said, "Lest perhaps the people change their minds when they see war, and return to Egypt." 18 So God led the people around by way of the wilderness of the Red Sea. And the children of Israel went up in orderly ranks out of the land of Egypt. 19 And Moses took the bones of Joseph with him, for he had placed the children of Israel under solemn oath, saying, "God will surely visit you, and you shall carry up my bones from here with you." 20 So they took their journey from Succoth and camped in Etham at the edge of the wilderness. 21 And the Lord went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night.

Commentary on Exodus 13:11-16

(Read Exodus 13:11-16)

The firstlings of beast not used in sacrifice, were to be changed for others so used, or they were to be destroyed. Our souls are forfeited to God's justice, and unless ransomed by the sacrifice of Christ, will certainly perish. These institutions would continually remind them of their duty, to love and serve the Lord. In like manner, baptism and the Lord's supper, if explained and attended to, would remind us, and give us occasion to remind one another of our profession and duty.

Commentary on Exodus 13:17-20

(Read Exodus 13:17-20)

There were two ways from Egypt to Canaan. One was only a few days' journey; the other was much further about, through the wilderness, and that was the way in which God chose to lead his people Israel. The Egyptians were to be drowned in the Red sea; the Israelites were to be humbled and proved in the wilderness. God's way is the right way, though it seems about. If we think he leads not his people the nearest way, yet we may be sure he leads them the best way, and so it will appear when we come to our journey's end. The Philistines were powerful enemies; it was needful that the Israelites should be prepared for the wars of Canaan, by passing through the difficulties of the wilderness. Thus God proportions his people's trials to their strength, 1 Corinthians 10:13. They went up in good order. They went up in five in a rank, some; in five bands, so others, which it seems rather to their faith and hope, that God would bring them to Canaan, in expectation of which they carried these bones with them while in the desert.

(Read Exodus 13:21-22)

The Lord went before them in a pillar, or appearance of the Divine Majesty. Christ was with the church in the wilderness, John 14:6.
