Do not be rash with your mouth, and do not let your heart be hasty to say a word before God. For God is in Heaven, and you are on earth; therefore let your words be few.

Do not allow your mouth to cause your flesh to sin; do not 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 mouth are gracious; but the lips of a fool will swallow him.

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