Ecclesiastes 9:14-16

There was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it:

Now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man.

Then said I, Wisdom is better than strength: nevertheless the poor man's wisdom is despised, and his words are not heard.
