Proverbs 26:6-8

New International Version - UK

⁶ Sending a message by the hands of a fool
    is like cutting off one’s feet or drinking poison.
⁷ Like the useless legs of one who is lame
    is a proverb in the mouth of a fool.
⁸ Like tying a stone in a sling
    is the giving of honour to a fool.
