Ecclesiastes 10:1-4

[1] Dead flies make the perfumer's ointment give off an evil odor;
so a little folly outweighs wisdom and honor.
[2] A wise man's heart inclines him toward the right, 
but a fool's heart toward the left.
[3] Even when the fool walks on the road, he lacks sense, 
and he says to every one that he is a fool.
[4] If the anger of the ruler rises against you, do not leave your place, 
for deference will make amends for great offenses.
