Proverbs 15: 1-4
A soft answer turneth away wrath: but grievous words stir up anger.
The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.
The eyes of the Lord are in every place, beholding the evil and the good.
A wholesome tongue is a tree of life: but perverseness therein is a breach in the spirit.
