Ecclesiastes 9:13-15

American Standard Version

¹³ I have also seen wisdom under the sun on this wise, 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.
