But I am saying to you°, Everyone who is vainly angry toward his brother will be liable to the judgment, and if he should say to his brother, Empty-head, will be liable to the council, but whoever says, Fool, will be liable to the fiery hell. {Hell (Gehenna) is listed under Definitions section.} {Vainly can be: with emptiness (without cause or reason; i.e., to further one’s own vanity)} {Mat 5:22: Jesus is showing the danger of using words to show contempt for or condemn others.}
