Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God. For God is in heaven, and thou upon earth. Therefore let thy words be few.

Do not allow thy mouth to cause thy flesh to sin, nor say thou before the [heavenly] agent, that is was an error. Why should God be angry at thy voice, and destroy the work of thy 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 himself up.

The beginning of the words of his mouth is foolishness, and the end of his talk is mischievous madness.
