some proverbs on speach

With his mouth the godless man would destroy his neighbor,
but by knowledge the righteous are delivered.

The mouth of the righteous is a fountain of life,
but the mouth of the wicked conceals violence.

The tongue of the righteous is choice silver;
the heart of the wicked is of little worth.
The lips of the righteous feed many,
but fools die for lack of sense.

The heart of the righteous ponders how to answer,
but the mouth of the wicked pours out evil things.
