Be not unwise with your mouth, and let not your heart be quick to say anything before God, because God is in heaven and you are on the earth--so let not the number of your words be great.

Let not your mouth make your flesh do evil. And say not before the angel, It was an error. So that God may not be angry with your words and put an end to the work of your hands.

All the work of man is for his mouth, and still he has a desire for food.

The words of a wise man's mouth are sweet to all, but the lips of a foolish man are his destruction.

The first words of his mouth are foolish, and the end of his talk is evil crime.
