22 The next generation, your children who come after you and the foreigner who comes from a far country, will be appalled when they see the widespread devastation, how God made the whole land sick. 23 They'll see a fire-blackened wasteland of brimstone and salt flats, nothing planted, nothing growing, not so much as a blade of grass anywhere - like the overthrow of Sodom and Gomorrah, Admah and Zeboiim, which God overthrew in fiery rage. 24 All the nations will ask, "Why did God do this to this country? What on earth could have made him this angry?"
Matthew Henry's Commentary on Deuteronomy 29:22-24
Commentary on Deuteronomy 29:22-28
(Read Deuteronomy 29:22-28)
Idolatry would be the ruin of their nation. It is no new thing for God to bring desolating judgments on a people near to him in profession. He never does this without good reason. It concerns us to seek for the reason, that we may give glory to God, and take warning to ourselves. Thus the law of Moses leaves sinners under the curse, and rooted out of the Lord's land; but the grace of Christ toward penitent, believing sinners, plants them again in their land; and they shall no more be pulled up, being kept by the power of God.
