Ecclesiastes 9:13-16 CSB

13 I have observed that this also is wisdom under the sun, and it is significant to me:
14 There was a small city with few men in it. A great king came against it, surrounded it, and built large siege works against it.
15 Now a poor wise man was found in the city, and he delivered the city by his wisdom. Yet no one remembered that poor man.
16 And I said, "Wisdom is better than strength, but the wisdom of the poor man is despised, and his words are not heeded."
