23 And that all the land is a salt and smoking waste, not planted or giving fruit or clothed with grass, but wasted like Sodom and Gomorrah, Admah and Zeboiim, on which the Lord sent destruction in the heat of his wrath:

Matthew Henry's Commentary on Deuteronomy 29:23

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.
