"And the tongue is a fire, a world of iniquity.  The tongue is placed among our members, which defileth the whole body, and inflameth the wheel of our nativity, being set on fire by hell.  For every nature of beasts, and of birds, and of serpents, and of the rest, is tamed, and hath been tamed, by the nature of man:  But the tongue no man can tame, an unquiet evil, full of deadly poison.  By it we bless God and the Father:  and by it we curse men, who are made after the likeness of God.  Out of the same mouth proceedeth blessing and cursing.  My brethren, these things ought not so to be."  (James 3:6-10)
