Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God: for God is in the heavens, and thou upon earth; therefore let thy words be few.

Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an inadvertence. Wherefore should God be wroth at thy voice, and destroy the work of thy hands?

All the labour 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 swallow up himself.

The beginning of the words of his mouth is folly; and the end of his talk is mischievous madness.
