Psalm 73:9

Who have said, “With our tongue we will prevail; Our lips are our own; who is lord over us?”

For Jerusalem has stumbled and Judah has fallen, Because their tongue and their deeds are against Yahweh, To rebel against His glorious presence.

They turn, but not upward; They are like a deceitful bow; Their princes will fall by the sword Because of the indignation of their tongue. This will be their scoffing in the land of Egypt.

So also the tongue is a small part of the body, and yet it boasts of great things. Behold how great a forest is set aflame by such a small fire!
