Proverbs 17:16-21

16It is senseless to pay to educate a fool, since he has no heart for learning.

17A friend is always loyal, and a brother is born to help in time of need.

18It’s poor judgment to guarantee another person’s debt or put up security for a friend.

19Anyone who loves to quarrel loves sin; anyone who trusts in high walls invites disaster.

20The crooked heart will not prosper; the lying tongue tumbles into trouble.

21It is painful to be the parent of a fool; there is no joy for the father of a rebel.
