It is joy to the just to do judgment: but destruction shall be to the workers of iniquity.
– Proverbs 21:15
The word for joy means gladness, or pleasure. Judgment refers to justice, or just dealing. It can mean a legal verdict in the official sense of justice, or it can refer to the just respect and treatment of others in our dealings. The word for destruction means ruin, or terror. The just and upright delight in justice being done and it terrifies the wicked, because they want justice to be bendable to their advantage (Proverbs 17:23). This proverb complements Proverbs 10:29 where the way of the Lord, which is the way of judgment, is a fortification for the upright but a terror to the wicked.
