Proverbs 16:27-31

²⁷A good-for-nothing man is a designer of evil, and in his lips there is a burning fire.

²⁸A man of twisted purposes is a cause of fighting everywhere: and he who says evil secretly makes trouble between friends.

²⁹A violent man puts desire of evil into his neighbour's mind, and makes him go in a way which is not good.

³⁰He whose eyes are shut is a man of twisted purposes, and he who keeps his lips shut tight makes evil come about.

³¹The grey head is a crown of glory, if it is seen in the way of righteousness.
