21 See how Jerusalem, once so faithful, has become a prostitute. Once the home of justice and righteousness, she is now filled with murderers. 22 Once like pure silver, you have become like worthless slag. Once so pure, you are now like watered-down wine. 23 Your leaders are rebels, the companions of thieves. All of them love bribes and demand payoffs, but they refuse to defend the cause of orphans or fight for the rights of widows. 24 Therefore, the Lord, the Lord of Heaven's Armies, the Mighty One of Israel, says, "I will take revenge on my enemies and pay back my foes! 25 I will raise my fist against you. I will melt you down and skim off your slag. I will remove all your impurities. 26 Then I will give you good judges again and wise counselors like you used to have. Then Jerusalem will again be called the Home of Justice and the Faithful City." 27 Zion will be restored by justice; those who repent will be revived by righteousness. 28 But rebels and sinners will be completely destroyed, and those who desert the Lord will be consumed. 29 You will be ashamed of your idol worship in groves of sacred oaks. You will blush because you worshiped in gardens dedicated to idols. 30 You will be like a great tree with withered leaves, like a garden without water. 31 The strongest among you will disappear like straw; their evil deeds will be the spark that sets it on fire. They and their evil works will burn up together, and no one will be able to put out the fire.

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?
