Be not rash with your mouth, nor let your heart be hasty to utter a word before God, for God is in heaven, and you upon earth; therefore let your words be few.
Let not your mouth lead you into sin, and do not say before the messenger that it was a mistake; why should God be angry at your voice, and destroy the work of your hands?
But I say to you that every one who is angry with his brother shall be liable to judgment; whoever insults his brother shall be liable to the council, and whoever says, ‘You fool!’ shall be liable to the hell of fire.
And the tongue is a fire. The tongue is an unrighteous world among our members, staining the whole body, setting on fire the cycle of nature, and set on fire by hell.
