'Mouths' in the Bible

And her latter end is bitter as wormwood, Sharp as a sword with mouths.

The mouth of the righteous flows with [skillful and godly] wisdom,But the perverted tongue will be cut out.

The lips of the upright man have knowledge of what is pleasing, but twisted are the mouths of evil-doers.

The heart of one who has understanding seeks knowledge, but the mouths of fools feed on folly.
