One who cuts off his own feet, drinking violence,
is a person who sends messages by the hand of a fool. Bible

This proverb warns about trusting a fool to do important work. If you chop off your own feet, you cannot deliver a message, but that is in effect what happens when you give the message to a fool—it will not arrive as you intended it to. If it does arrive at all, it will be so mangled that it will cause harm, not be helpful. The wording in the RASV parallels the form of words in the Hebrew text.
