Proverbs 10:11

The mouth of the righteous is a fountain of life,

But the mouth of the wicked covers up violence.

Proverbs 10:13

On the lips of the one who has understanding, wisdom is found,

But a rod is for the back of him who lacks a heart of wisdom.

Wise men store up knowledge,

But the mouth of the ignorant fool draws ruin near.

The tongue of the righteous is as choice silver,

The heart of the wicked is worth little.

The lips of the righteous feed many,

But ignorant fools die for lack of a heart of wisdom.

The mouth of the righteous bears wisdom,

But the tongue of perversions will be cut out.

The lips of the righteous know what is acceptable,

But the mouth of the wicked what is perverse.
