In order to lead him into the spring and original of them, and to acquaint him with the goodness of God, which laid them under obligation to observe them:

we were Pharaoh's bondmen in Egypt; were brought into bondage and slavery to Pharaoh king of Egypt, into whose country their ancestors came, and where they resided many years, and at length were reduced to the utmost servitude and misery:

and the Lord brought us out of Egypt with a mighty hand; by the exertion of his mighty power, which the Egyptians and their king could not withstand, as a token of his care and kindness to us; by the ties of which we are bound in gratitude to observe his commands. The Targum of Jonathan is,"the Word of the Lord brought us, &c.''and it was Christ the Son of God that was from first to last concerned in that affair, even from the appearance to Moses in the bush to Israel's coming out of Egypt.

Then thou shalt say unto thy son, We were Pharaoh's bondmen in Egypt; and the LORD brought us out of Egypt with a mighty hand:

6:17-25 Moses gives charge to keep God's commandments. Negligence will ruin us; but we cannot be saved without diligence. It is our interest, as well as our duty, to be religious. It will be our life. Godliness has the promise of the continuance and comfort of the life that now is, as far as it is for God's glory. It will be our righteousness. It is only through the Mediator we can be righteous before God. The knowledge of the spirituality and excellency of the holy law of God, is suited to show sinful man his need of a Saviour, and to prepare his heart to welcome a free salvation. The gospel honours the law, not only in the perfect obedience of the Son of God, the Lord Jesus Christ; but in that it is a plan for bringing back apostate rebels and enemies, by repentance, faith, forgiveness, and renewing grace, to love God above all things, even in this world; and in the world above, to love him perfectly, even as angels love him.
