22 "Then the generations to come, both your own descendants and the foreigners who come from distant lands, will see the devastation of the land and the diseases the Lord inflicts on it. 23 They will exclaim, 'The whole land is devastated by sulfur and salt. It is a wasteland with nothing planted and nothing growing, not even a blade of grass. It is like the cities of Sodom and Gomorrah, Admah and Zeboiim, which the Lord destroyed in his intense anger.' 24 "And all the surrounding nations will ask, 'Why has the Lord done this to this land? Why was he so angry?'

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.
