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 people in it. A great king came against it and besieged it, building great siegeworks against it. 15 Now 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 So I said, "Wisdom is better than might; yet the poor man's wisdom is despised, and his words are not heeded." 17 The quiet words of the wise are more to be heeded than the shouting of a ruler among fools. 18 Wisdom is better than weapons of war, but one bungler destroys much good.

Commentary on Ecclesiastes 9:13-18
(Read Ecclesiastes 9:13-18)
A man may, by his wisdom, bring to pass that which he could never do by his strength. If God be for us, who can be against us, or stand before us? Solomon observes the power of wisdom, though it may labour under outward disadvantages. How forcible are right words! But wise and good men must often content themselves with the satisfaction of having done good, or, at least, endeavoured to do it, when they cannot do the good they would, nor have the praise they should. How many of the good gifts, both of nature and Providence, does one sinner destroy and make waste! He who destroys his own soul destroys much good. One sinner may draw many into his destroying ways. See who are the friends and enemies of a kingdom or a family, if one saint does much good, and one sinner destroys much good.
