And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defiles the whole body, and sets on fire the course of nature; and it is set on fire by hell. For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and has been tamed by mankind: But the tongue can no man tame; it is an unruly evil, full of deadly poison. With this bless we God, even the Father; and with this curse we men, who are made after the similitude of God. (James 3:6-9)
