“Cumque interrogaverit te filius tuus cras, dicens : Quid est hoc ? respondebis ei : In manu forti eduxit nos Dominus de terra Ægypti, de domo servitutis.”
“And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the LORD brought us out from Egypt, from the house of bondage: in: Heb. to morrow”
“In the future, when your son asks you, ‘What does this mean?’ you are to tell him, ‘With a mighty hand the LORD brought us out of Egypt, out of the house of slavery.”
“It shall be, when your son asks you in time to come, saying, ‘What is this?’ that you shall tell him, ‘By strength of hand Yahweh brought us out from Egypt, from the house of bondage.”

II. Further directions concerning the catechising of their children, and all those of the rising generation, from time to time, in this matter. It is supposed that, when they saw all the firstlings thus devoted, they would ask the meaning of it, and their parents and teachers must tell them (v. 14-16) that God's special propriety in their firstborn, and all their firstlings, was founded in his special preservation of them from the sword of the destroying angel. Being thus delivered, they must serve him. Note, 1. Children should be directed and encouraged to ask their parents questions concerning the things of God, a practice which would be perhaps of all others the most profitable way of catechising; and parents must furnish themselves with useful knowledge, that they may be ready always to give an answer to their enquiries. If ever the knowledge of God cover the earth, as the waters do the sea, the fountains of family-instruction must first be broken up. 2. We should all be able to show cause for what we do in religion. As sacraments are sanctified by the word, so they must be explained and understood by it. God's service is reasonable, and it is then acceptable when we perform it intelligently, knowing what we do and why we do it. 3. It must be observed how often it is said in this chapter that by strength of hand (v. 3, 14, 16), with a strong hand (v. 9), the Lord brought them out of Egypt. The more opposition is given to the accomplishment of God's purposes the more is his power magnified therein. It is a strong hand that conquers hard hearts. Sometimes God is said to work deliverance not by might nor power (Zech 4 6), not by such visible displays of his power as that recorded here. 4. Their posterity that should be born in Canaan are directed to say, The Lord brought us out of Egypt, v. 14, 16. Mercies to our fathers are mercies to us; we reap the benefit of them, and therefore must keep up a grateful remembrance of them. We stand upon the bottom of former deliverances, and were in the loins of our ancestors when they were delivered. Much more reason have we to say that in the death and resurrection of Jesus Christ we were redeemed.
17 And it came to pass, when Pharaoh had let the people go, that God led them not through the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt: 18 But God led the people about, through the way of the wilderness of the Red sea: and the children of Israel went up harnessed out of the land of Egypt. 19 And Moses took the bones of Joseph with him: for he had straitly sworn the children of Israel, saying, God will surely visit you; and ye shall carry up my bones away hence with you. 20 And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. 21 And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: 22 He took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people.
Verses 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.
