Proverbs 28:16
The prince that wanteth understanding is also a great oppressor: but he that hateth covetousness shall prolong his days. The prince that wanteth understanding is also a great oppressor: but he that hateth covetousness shall prolong his days.
This saying stands within chapters 25-29, Hezekiah's collection of Solomon's proverbs gathered about three hundred years after Solomon.
A prince or ruler who lacks understanding becomes a great oppressor and acts oppressively.
The one who hates covetousness will have prolonged days and a long life.
Lacking understanding means failing to understand what is right, as illustrated when rich people become self-conceited and despise the poor.
Covetousness is rooted in selfishness that fixes a person's thoughts on personal possessions and needs and turns them away from others, God, and God's work.
Covetousness is a sin that must be forsaken.
