Proverbs 17:18-20

Complete Jewish Bible

¹⁸ He who gives his hand to guarantee a loan
    for his neighbor lacks good sense.

¹⁹ Those who love quarreling love giving offense;
    those who make their gates tall are courting disaster.

²⁰ A crooked-hearted person will find nothing good,
    and the perverse of speech will end in calamity.
