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.
21. Though warned by the judgment on their fathers, the next generation also rebelled against God. The "kindness of Israel's youth and love of her espousals in the wilderness" (Jer 2:2, 3) were only comparative (the corruption in later times being more general), and confined to the minority; as a whole, Israel at no time fully served God. The "children" it was that fell into the fearful apostasy on the plains of Moab at the close of the wilderness sojourn (Nu 25:1, 2; De 31:27).
