Ecclesiastes 10:1-3; Ecclesiastes 10:12-15
As dead flies spoil the perfumer's oil, so a little folly outweighs wisdom and honor.
The mind of the wise tends toward the right, but the mind of the fool toward the left.
Fools lack all sense even when they walk down the street; they show everyone that they are fools.
Words from a wise person's mouth are beneficial, but fools are devoured by their own lips.
Fools start out talking foolishness and end up speaking awful nonsense.
Fools talk too much! No one knows what will happen; no one can say what will happen in the future.
The hard work of fools tires them out because they don't even know the way to town!
