Proverbs 26:5-7

New Living Translation

⁵ Be sure to answer the foolish arguments of fools,
    or they will become wise in their own estimation.

⁶ Trusting a fool to convey a message
    is like cutting off one’s feet or drinking poison!

⁷ A proverb in the mouth of a fool
    is as useless as a paralyzed leg.
