Proverbs 26:7-9

⁷A lame man cannot use his legs, and similarly SIM it is useless for a foolish person to speak MTY ◄proverbs/wise sayings►.

⁸Tying a stone in a sling so that it cannot be thrown at a target is as foolish as SIM honoring a foolish person.

⁹If a drunk person waves some thorns/brambles with his hand, he is not able to accomplish anything useful by doing that (OR, he does not feel it when a thorn sticks in his hand); similarly, if foolish people speak MTY proverbs, they do not help anyone who hears them.
