Ecclesiastes 9:13-16

This [illustration of] wisdom I have also seen under the sun, and great it was to me: There was a little city with few men in it and a great king came against it and besieged it and built great battlements against it. 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.
