²⁰ He that hath a froward heart findeth no good: and he that hath a perverse tongue falleth into mischief.

⁶ A fool's lips enter into contention, and his mouth calleth for strokes.

⁷ A fool's mouth is his destruction, and his lips are the snare of his soul.

³¹ The mouth of the just bringeth forth wisdom: but the froward tongue shall be cut out.

⁶ 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.

⁷ For every kind of beasts, and of birds, and of serpents, and of things in the sea, is tamed, and hath been tamed of mankind:

⁸ But the tongue can no man tame; it is an unruly evil, full of deadly poison.

¹² The words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself.
