Ecclesiastes 9:13 - 10:15 (ESV)
9:13 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 heard.
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.
10:1 Dead flies make the perfumer's ointment give off a stench; so a little folly outweighs wisdom and honor.
2 A wise man's heart inclines him to the right,
but a fool's heart to the left.
3 Even when the fool walks on the road, he lacks sense,
and he says to everyone that he is a fool.
4 If the anger of the ruler rises against you, do not leave your place,
for calmness will lay great offenses to rest.
5 There is an evil that I have seen under the sun, as it were an error proceeding from the ruler: 6 folly is set in many high places, and the rich sit in a low place. 7 I have seen slaves on horses, and princes walking on the ground like slaves.
8 He who digs a pit will fall into it,
and a serpent will bite him who breaks through a wall.
9 He who quarries stones is hurt by them,
and he who splits logs is endangered by them.
10 If the iron is blunt, and one does not sharpen the edge,
he must use more strength,
but wisdom helps one to succeed.
11 If the serpent bites before it is charmed,
there is no advantage to the charmer.
12 The words of a wise man's mouth win him favor,
but the lips of a fool consume him.
13 The beginning of the words of his mouth is foolishness,
and the end of his talk is evil madness.
14 A fool multiplies words,
though no man knows what is to be,
and who can tell him what will be after him?
15 The toil of a fool wearies him,
for he does not know the way to the city.
