Proverbs 13:15-17

Amplified Bible

¹⁵ 
Good understanding wins favor [from others],
But the way of the unfaithful is hard [like barren, dry soil].
¹⁶ 
Every prudent and self-disciplined man acts with knowledge,
But a [closed-minded] fool [who refuses to learn] displays his foolishness [for all to see].
¹⁷ 
A wicked messenger falls into hardship,
But a faithful ambassador brings healing.
