Proverbs 15:1-4

¹Anger slays even wise men; yet a submissive answer turns away wrath: but a grievous word stirs up anger.

²The tongue of the wise knows what is good: but the mouth of the foolish tells out evil things.

³The eyes of the Lord behold both the evil and the good in every place.

⁴The wholesome tongue is a tree of life, and he that keeps it shall be filled with understanding.
