Ecclesiastes 9:13-18

Also this I came to see as wisdom under the sun, and it impressed me. There was a small city with few men in it and a great king came to it, surrounded it and constructed large siegeworks against it. But there was found in it a poor wise man and he delivered the city by his wisdom. Yet no one remembered that poor man. So I said, “Wisdom is better than strength.” But the wisdom of the poor man is despised and his words are not heeded. The words of the wise heard in quietness are better than the shouting of a ruler among fools. Wisdom is better than weapons of war, but one sinner destroys much good.
