Ecclesiastes 9:15-18

But there was found in it a poor wise man, and by his wisdom he rescued the city. Yet no man [seriously] remembered that poor man. But I say that wisdom is better than strength, though the poor man’s wisdom is despised and his words are not heeded. The words of wise men heard in quietness are better than the shouting of one who rules among fools. Wisdom is better than weapons of war, but one sinner destroys much good.
