Proverbs 21:22

22. The city of the mighty עיר , ( ‘ hir,) גברים ( gibborim.) It may mean a very strong city, or a city defended by mighty men, or both.

The strength of the confidence thereof Or, the bulwark of its confidence “its trusted strength.” He casts down the strong defences in which the defenders confided. The proverb means that wisdom is better than physical strength; skilful strategy more powerful than brute force: accomplishes more than force of arms. History is full of illustrations. Compare Ecclesiastes 9:14-16; Proverbs 24:5. In 2 Corinthians 10:4, the apostle uses the very words of the Septuagint here in respect to the “pulling down” of the spiritual strongholds. The heavenly wise men, who were “mighty” through God, overturned the strong towers of heathenism.
