Ecclesiastes 9:16

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.

The words of wise men are heard in quiet more than the cry of him that ruleth among fools.

Wisdom is better than weapons of war: but one sinner destroyeth much good.
