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:
Ecclesiastes 9:14, King James Version
In context
13 This wisdom have I seen also under the sun, and it seemed great unto me:
14 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:
15 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.
