A wicked man takes a covert bribe to subvert the course of justice.

Ecclesiastes 4:1
Again I looked, and I considered all the oppression taking place under the sun. I saw the tears of the oppressed, and they had no comforter; the power lay in the hands of their oppressors, and there was no comforter.

Ecclesiastes 5:8
If you see the oppression of the poor and the denial of justice and righteousness in the province, do not be astonished at the matter; for one official is watched by a superior, and others higher still are over them.

Ecclesiastes 8:9
All this I have seen, applying my mind to every deed that is done under the sun; there is a time when one man lords it over another to his own detriment.

Surely oppression makes a wise man mad; and a gift destroys the heart.
