James 3:8

"Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:"

"They have sharpened their tongues like a serpent; adders' poison is under their lips. Selah."

"The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords."

"And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell."

"My soul is among lions: and I lie even among them that are set on fire, even the sons of men, whose teeth are spears and arrows, and their tongue a sharp sword."

"Behold, they belch out with their mouth: swords are in their lips: for who, say they, doth hear?"

"Their poison is like the poison of a serpent: they are like the deaf adder that stoppeth her ear;"

"Their wine is the poison of dragons, and the cruel venom of asps."

"Surely the serpent will bite without enchantment; and a babbler is no better."
