The Judgment and Redemption of Zion

21 See how the faithful city has become a prostitute! She once was full of justice; righteousness used to dwell in her- but now murderers! 22 Your silver has become dross, your choice wine is diluted with water. 23 Your rulers are rebels, partners with thieves; they all love bribes and chase after gifts. They do not defend the cause of the fatherless; the widow's case does not come before them. 24 Therefore the Lord, the Lord Almighty, the Mighty One of Israel, declares: "Ah! I will vent my wrath on my foes and avenge myself on my enemies. 25 I will turn my hand against you;[1]I will thoroughly purge away your dross and remove all your impurities.

Matthew Henry's Commentary on Isaiah 1:21-25

Commentary on Isaiah 1:21-31

(Read Isaiah 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?
