Proverbs 10:11

The mouth of the righteous is a fountain of life,

But the mouth of the wicked covers up violence.

Proverbs 15:4

A tongue that brings healing is a tree of life,

But perversion in it breaks the spirit.

A man has gladness in an apt answer,

And how good is a timely word!

The heart of the wise gives insight to his mouth

And increases learning to his lips.

Pleasant words are a honeycomb,

Sweet to the soul and healing to the bones.

The words of a man’s mouth are deep waters;

The fountain of wisdom is a flowing brook.

Death and life are in the power of the tongue,

And those who love it will eat its fruit.

Like an earthen vessel overlaid with silver dross

Are fiery lips and an evil heart.
