Proverbs 10:17-21

He is in the way of life that keepeth instruction: but he that refuseth reproof erreth.

He that hideth hatred with lying lips, and he that uttereth a slander, is a fool.

In the multitude of words there wanteth not sin: but he that refraineth his lips is wise.

The tongue of the just is as choice silver: the heart of the wicked is little worth.

The lips of the righteous feed many: but fools die for want of wisdom.
