Proverbs 15:1; Proverbs 17:27; Proverbs 25:15

15  dA soft answer turns away wrath,

but ea harsh word stirs up anger.

27  Whoever wrestrains his words has knowledge,

and he who has a cool spirit is a man of understanding.

15  With epatience a ruler may be persuaded,

and a soft tongue will break a bone.
