Proverbs 14:5

2 Whoever walks in uprightness fears the Lord, but he who is devious in his ways despises him. 3 By the mouth of a fool comes a rod for his back, but the lips of the wise will preserve them. 4 Where there are no oxen, the manger is clean, but abundant crops come by the strength of the ox.

5 A faithful witness does not lie, but a false witness breathes out lies. 6 A scoffer seeks wisdom in vain, but knowledge is easy for a man of understanding. 7 Leave the presence of a fool, for there you do not meet words of knowledge. 8 The wisdom of the prudent is to discern his way, but the folly of fools is deceiving.
