Psalm 73:8

In his lofty pride the wicked hotly pursues the afflicted; Let them be caught in the thoughts which they have devised.

His mouth is full of curses and deceit and oppression; Under his tongue is mischief and wickedness.

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

They have closed their unfeeling heart, With their mouth they speak proudly.

‘Violence has grown into a rod of wickedness. None of them shall remain, none of their multitude, none of their moaning, nor anything eminent among them.

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!
