As a roaring lion, and a ranging bear; so is a wicked ruler over the poor people. The prince that wanteth understanding is also a great oppressor: but he that hateth covetousness shall prolong his days. (Proverbs 28:15-16)
If a ruler hearken to lies, all his servants are wicked. (Proverbs 29:12)
Righteousness exalteth a nation: but sin is a reproach to any people. (Proverbs 14:34)
The king by judgment establisheth the land: but he that receiveth gifts overthroweth it. (Proverbs 29:4)
