Ecclesiastes 9:13-15

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

¹⁴There 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:

¹⁵Now 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.
