Be not rash with your mouth, and let not your heart be hasty to utter anything before God: for God is in heaven, and you upon earth: therefore let your words be few.

Permit not your mouth to cause your flesh to sin; neither say before the angel, that it was an error: why should God be angry at your voice, and destroy the work of your hands?

All the labor of man is for his mouth, and yet the appetite is not filled.

The words of a wise man's mouth are gracious; but the lips of a fool will swallow him up.

The beginning of the words of his mouth is foolishness: and the end of his talk is wicked madness.
