Matthew Poole and continuators on Proverbs 26:6

6 He that sendeth a message by the hand of a fool , cutteth off the feet , and drinketh damage .

He that employeth a Fool upon any important Errant or Business which is too hard for him.

To wit, of his Messenger, he bids one go that wants Legs, he sends one who wants that discretion, which is as necessary for that employment as Legs are for going.

He bringeth upon himself abundance of loss and mischief, not onely spoiling that business about which he sends him, but making himself contemptible to the Person to whom he sends him, and to others with him, as if he had not common prudence to chuse a fit Messenger, and giving occasion by the folly of his Messenger to further misunderstandings, and jealousies, and inconveniences. For the Phrase, we may observe that drinking in Scripture frequently notes the plentiful doing or receiving of any thing, as they who multiply sins are said to drink Iniquity like Water, Iob 15. 16. & 34. 7. and they who are greatly afflicted are commonly said to drink the Cup.
