James 3:6-8

EJ2000(i) 6 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 our nature; and it is set on fire of hell. 7 For every nature of beasts and of birds and of serpents and of beings in the sea may be tamed and is tamed by mankind, 8 but no man can tame the tongue, which is an evil that cannot be restrained and is full of deadly poison.
