22 And the generation to come, your children that shall rise up after you, and the foreigner that shall come from a far land, shall say, when they see the plagues of that land, and the sicknesses wherewith Jehovah hath made it sick; 23 [and that] the whole land thereof is brimstone, and salt, [and] a burning, [that] it is not sown, nor beareth, nor any grass groweth therein, like the overthrow of Sodom and Gomorrah, Admah and Zeboiim, which Jehovah overthrew in his anger, and in his wrath: 24 even all the nations shall say, Wherefore hath Jehovah done thus unto this land? what meaneth the heat of this great anger?

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.
