Proverbs 14:4-6

Amplified Bible

⁴ 
Where there are no oxen, the manger is clean,
But much revenue [because of good crops] comes by the strength of the ox.
⁵ 
A faithful and trustworthy witness will not lie,
But a false witness speaks lies.
⁶ 
A scoffer seeks wisdom and finds none [for his ears are closed to wisdom],
But knowledge is easy for one who understands [because he is willing to learn].
