I. The great things God did for them, which he puts them in mind of, not as grudging them his favours, but to show how ungrateful they had been. And we say, If you call a man ungrateful, you can call him no worse. It was a great favour, 1. That God brought them forth out of Egypt (v. 10), though, as it follows, he brought them into the wilderness and not into Canaan immediately. It is better to be at liberty in a wilderness than bond-slaves in a land of plenty, to enjoy God and ourselves in solitude than to lose both in a crowd; yet there were many of them who had such base servile spirits as not to understand this, but, when they met with the difficulties of a desert, wished themselves in Egypt again. 2. That he gave them the law upon Mount Sinai (v. 11), not only instructed them concerning good and evil, but by his authority bound them from the evil and to the good. He gave them his statutes, and a valuable gift it was. Moses commanded them a law that was the inheritance of the congregation of Israel, Deut. xxxiii. 4. God made them to know his judgments, not only enacted laws for them, but showed them the reasonableness and equity of those laws, with what judgment they were formed. The laws he gave them they were encouraged to observe and obey; for, if a man do them, he shall even live in them; in keeping God's commandments there is abundance of comfort and a great reward. Christ says, If thou wilt into enter life, and enjoy it, keep the commandments. Though those who are the most strict in their obedience are thus far unprofitable servants that they do no more than is their duty to do, yet it is thus richly recompensed: This do, and thou shalt live. The Chaldee says, He shall live an eternal life in them. St. Paul quotes this (Gal. iii. 12) to show that the law is not of faith, but proposes life upon condition of perfect obedience, which we are not capable of rendering, and therefore must have recourse to the grace of the gospel, without which we are all undone. 3. That he revived the ancient institution of the sabbath day, which was lost and forgotten while they were bond-slaves in Egypt; for their task-masters there would by no means allow them to rest one day in seven. In the wilderness indeed every day was a day of rest; for what need had those to labour who lived upon manna, and whose raiment waxed not old? But one day in seven must be a holy rest (v. 12): I gave them my sabbaths to be a sign between me and them (the institution of the sabbath was a sign of God's good-will to them, and their observance of it a sign of their regard to him), that they might know that I am the Lord that sanctify them. By this God made it to appear that he had distinguished them from the rest of the world, and designed to model them for a peculiar people to himself; and by their attendance on God in solemn assemblies on sabbath days they were made to increase in the knowledge of God, in an experimental knowledge of the powers and pleasures of his sanctifying grace. Note, (1.) Sabbaths are privileges, and are so to be accounted; the church acknowledges as a great favour, in that chapter which is parallel to this and seems to have a reference to this (Neh. ix. 14), Thou madest known unto them thy holy sabbaths. (2.) Sabbaths are signs; it is a sign that men have a sense of religion, and that there is some good correspondence between them and God, when they make conscience of keeping holy and sabbath day. (3.) Sabbaths, if duly sanctified, are the means of our sanctification; if we do the duty of the day, we shall find, to our comfort, it is the Lord that sanctifies us, makes us holy (that is, truly happy) here, and prepares us to be happy (that is, perfectly holy) hereafter.
