Proverbs 14:3-7

³From the mouth of a fool comes an offshoot of his pride, but the lips of the wise will preserve them.

⁴Where there are no cattle the feeding trough is clean, but an abundant crop can come by the strength of an ox.

⁵A faithful witness does not lie, but a false witness breathes out lies.

⁶A mocker seeks wisdom and there is none, but knowledge comes easy to the one who is discerning.

⁷Walk away from a foolish person, for you will not find knowledge on his lips.
