I have also seen this example of wisdom under the sun, and it seemed great to me.
There was a little city with few men in it; and a great king came against it and besieged it, building great siegeworks against it.
But there was found in it a poor wise man, and he by his wisdom delivered the city. Yet no one remembered that poor man.
But I say that wisdom is better than might, though the poor man's wisdom is despised, and his words are not heeded.
