A fool's lips enter into contention, and his mouth calleth for strokes. A fool's mouth is his destruction, and his lips are the snare of his soul.

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

For the froward is abomination to the LORD: but his secret is with the righteous.

He that winketh with the eye causeth sorrow: but a prating fool shall fall.

The fear of the LORD is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate.

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

A naughty person, a wicked man, walketh with a froward mouth. He winketh with his eyes, he speaketh with his feet, he teacheth with his fingers; Frowardness is in his heart, he deviseth mischief continually; he soweth discord. Therefore shall his calamity come suddenly; suddenly shall he be broken without remedy.

With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself froward.

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

Wise men lay up knowledge: but the mouth of the foolish is near destruction.
