Ecclesiastes 9:14

9:13 This wisdom I have also seen under the sun, and it seemed great to me:

9:14 There was a little city with few men in it; and a great king came against it, besieged it, and built great snares around it.

9:15 Now there was found in it a poor wise man, and he by his wisdom delivered the city. Yet no one remembered that same poor man.
