Proverbs 10:11-21
[11]A good person’s words are a fountain of life, but a wicked person’s words hide a violent nature.
[12]Hate stirs up trouble, but love overlooks all offences.
[13]Intelligent people talk sense, but stupid people need to be punished.
[14]The wise get all the knowledge they can, but when fools speak, trouble is not far off.
[15]Wealth protects the rich; poverty destroys the poor.
[16]The reward for doing good is life, but sin leads only to more sin.
[17]People who listen when they are corrected will live, but those who will not admit that they are wrong are in danger.
[18]Anyone who hides hatred is a liar. Anyone who spreads gossip is a fool.
[19]The more you talk, the more likely you are to sin. If you are wise, you will keep quiet.
[20]A good person’s words are like pure silver; a wicked person’s ideas are worthless.
[21]A good person’s words will benefit many people, but you can kill yourself with stupidity.
