Ecclesiastes 10:2-10

²The heart of the wise man goes in the right direction; but the heart of a foolish man in the wrong.

³And when the foolish man is walking in the way, he has no sense and lets everyone see that he is foolish.

⁴If the wrath of the ruler is against you, keep in your place; in him who keeps quiet even great sins may be overlooked.

⁵There is an evil which I have seen under the sun, like an error which comes by chance from a ruler:

⁶The foolish are placed in high positions, but men of wealth are kept low.

⁷I have seen servants on horses, and rulers walking on the earth as servants.

⁸He who makes a hole for others will himself go into it, and for him who makes a hole through a wall the bite of a snake will be a punishment.

⁹He who gets out stones from the earth will be damaged by them, and in the cutting of wood there is danger.

¹⁰If the iron has no edge, and he does not make it sharp, then he has to put out more strength; but wisdom makes things go well.
