Ecclesiastes 9:13-18

[13] I have also seen this example of wisdom under the sun, and it seemed great to me.
[14] 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.
[15] 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.
[16] But I say that wisdom is better than might, though the poor man's wisdom is despised, and his words are not heeded.
[17] The words of the wise heard in quiet are better than the shouting of a ruler among fools.
[18] Wisdom is better than weapons of war, but one sinner destroys much good.
