And I gave them my statutes, and shewed them my judgments, which if a man do, he shall even live in them.

shewed...: Heb. made them to know

Jamieson-Fausset-Brown Bible Commentary

11. which if a man do, he shall . five in them-not "by them," as though they could justify a man, seeing that man cannot render the faultless obedience required (Le 18:5; Ga 3:12). "By them" is the expression indeed in Ro 10:5; but there the design is to show that, if man could obey all God's laws, he would be justified "by them" (Ga 3:21); but he cannot; he therefore needs to have justification by "the Lord our righteousness" (Jer 23:6); then, having thus received life, he "lives," that is, maintains, enjoys, and exercises this life only in so far as he walks "in" the laws of God. So De 30:15, 16. The Israelites, as a nation, had life already freely given to them by God's covenant of promise; the laws of God were designed to be the means of the outward expression of their spiritual life. As the natural life has its healthy manifestation in the full exercise of its powers, so their spiritual being as a nation was to be developed in vigor, or else decay, according as they did, or did not, walk in God's laws.

Matthew Henry's Concise Commentary

20:10-26. The history of Israel in the wilderness is referred to in the new Testament as well as in the Old, for warning. God did great things for them. He gave them the law, and revived the ancient keeping of the sabbath day. Sabbaths are privileges; they are signs of our being his people. If we do the duty of the day, we shall find, to our comfort, it is the Lord that makes us holy, that is, truly happy, here; and prepares us to be happy, that is, perfectly holy, hereafter. The Israelites rebelled, and were left to the judgments they brought upon themselves. God sometimes makes sin to be its own punishment, yet he is not the Author of sin: there needs no more to make men miserable, than to give them up to their own evil desires and passions.
