Isaiah 3:9

The shew of their countenance. Literally, “their regard for faces,” meaning “their partiality” (see Acts 10:34). Right or wrong was without meaning for these evil men; they did as they pleased. Justice did not count, only expediency. Their attitude and their deeds bore witness against them in the sight of Heaven.

Their sin as Sodom. The men of Sodom were open sinners. The city was notorious for its wickedness, and the people took delight in their reputation for evil. There was no pretense of right action — nothing but blatant iniquity openly flaunted before the world. This class of sinners was in open rebellion against God, and made no attempt to hide the fact. At this stage, vice no longer paid homage to virtue by making a pretense of goodness. There was an open display of vice and iniquity, an utter shamelessness in the doing of wrong. The cities of Israel were like the cities of the plain in their profligacy, and were ripe for destruction.

Rewarded evil. Sin sows the seeds of its own destruction. A sinner’s wickedness calls for a cup of bitterness and evil that will burn his soul and destroy his being. All who do wrong reward themselves with evil, not good.
