James 3:5-9

5In the same way, the tongue is a small part of the body, but it boasts of great things. Consider how small a spark sets a great forest ablaze. 6The tongue also is a fire, a world of wickedness among the parts of the body. It pollutes the whole person, sets the course of his life on fire, and is itself set on fire by hell.1

7All kinds of animals, birds, reptiles, and creatures of the sea are being tamed and have been tamed by man, 8but no man can tame the tongue. It is a restless evil, full of deadly poison.

9With the tongue we bless our Lord and Father, and with it we curse men, who have been made in God’s likeness.
