(30) Ye shall be . . .--Men were to think of the pleasant places that had tempted them, not as they had seen them, fresh and green, but as burnt up and withered, and then were to see in that desolation a parable of their own future. The word for "strong" occurs only in Amos 2:9, where we find "strong as the oaks."

Verse 30. - Ye shall be as an oak, etc. Contrast the case of the godly, whose "leaf shall not wither" (Psalm 1:3).

1:21-31 Neither holy cities nor royal ones are faithful to their trust, if religion does not dwell in them. Dross may shine like silver, and the wine that is mixed with water may still have the colour of wine. Those have a great deal to answer for, who do not help the oppressed, but oppress them. Men may do much by outward restraints; but only God works effectually by the influences of his Spirit, as a Spirit of Judgment. Sin is the worst captivity, the worst slavery. The redemption of the spiritual Zion, by the righteousness and death of Christ, and by his powerful grace, most fully accord with what is here meant. Utter ruin is threatened. The Jews should become as a tree when blasted by heat; as a garden without water, which in those hot countries would soon be burned up. Thus shall they be that trust in idols, or in an arm of flesh. Even the strong man shall be as tow; not only soon broken, and pulled to pieces, but easily catching fire. When the sinner has made himself as tow and stubble, and God makes himself as a consuming fire, what can prevent the utter ruin of the sinner?For ye shall be as an oak whose leaf fadeth,.... Shall be stripped of all their dependencies and self confidence, and be as naked and as bare as an oak that has cast its leaves; or thus, in a way of just retaliation, since they have desired oaks, and sacrificed under them, they shall be like them as in the wintertime, stripped of all their riches, honour, substance, and desirable things; see Revelation 18:12.

and as a garden that hath no water; in which the herbs and plants are dried up and withered: it signifies the uncomfortable condition such shall be in, as before.
