Proverbs 16:23-27

The heart of the wise teacheth his mouth, and addeth learning to his lips.

Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.

There is a way that seemeth right unto a man, but the end thereof are the ways of death.

He that laboureth laboureth for himself; for his mouth craveth it of him.

An ungodly man diggeth up evil: and in his lips there is as a burning fire.
