Ecclesiastes 9:13-16

13This also have I seen as wisdom under the sun, and it was great unto me.

14There was a little city, and few men within it; and there came a great king against it, and encompassed it, and built great bulwarks against it:

15and there was found in it a poor wise man, who by his wisdom delivered the city; but no man remembered that poor man.

16Then said I, Wisdom is better than strength; but the poor man's wisdom is despised, and his words are not heard.
