Psalms 37:30

37:30 The godly speak wise words

and promote justice.

Proverbs 12:18

12:18 Speaking recklessly is like the thrusts of a sword,

but the words of the wise bring healing.

James 3:5-6

3:5 So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze. 3:6 And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence – and is set on fire by hell.
