who conceives destructive plans,

and gives birth to harmful lies –

may the harm done by their lips overwhelm them!

their belly prepares deception.”

12:34 Offspring of vipers! How are you able to say anything good, since you are evil? For the mouth speaks from what fills the heart.

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.
