James 3:6-8
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.
3:7 For every kind of animal, bird, reptile, and sea creature is subdued and has been subdued by humankind.
3:8 But no human being can subdue the tongue; it is a restless evil, full of deadly poison.
