6 He that sendeth a message by the hand of a fool cutteth off the feet, and drinketh damage.   7 The legs of the lame are not equal: so is a parable in the mouth of fools.   8 As he that bindeth a stone in a sling, so is he that giveth honour to a fool.   9 As a thorn goeth up into the hand of a drunkard, so is a parable in the mouth of fools.

      To recommend wisdom to us, and to quicken us to the diligent use of all the means for the getting of wisdom, Solomon here shows that fools are fit for nothing; they are either sottish men, who will never think and design at all, or vicious men, who will never think and design well. 1. They are not fit to be entrusted with any business, not fit to go on an errand (v. 6): He that does but send a message by the hand of a fool, of a careless heedless person, one who is so full of his jests and so given to his pleasures that he cannot apply his mind to any thing that is serious, will find his message misunderstood, the one half of it forgotten, the rest awkwardly delivered, and so many blunders made about it that he might as well have cut off his legs, that is, never have sent him. Nay, he will drink damage; it will be very much to his prejudice to have employed such a one, who, instead of bringing him a good account of his affairs, will abuse him and put a trick upon him; for, in Solomon's language, a knave and a fool are of the same signification. It will turn much to a man's disgrace to make use of the service of a fool, for people will be apt to judge of the master by his messenger. 2. They are not fit to have any honour put upon them. He had said (v. 1), Honour is not seemly for a fool; here he shows that it is lost and thrown away upon him, as if a man should throw a precious stone, or a stone fit to be used in weighing, into a heap of common stones, where it would be buried and of no use; it is as absurd as if a man should dress up a stone in purple (so others); nay, it is dangerous, it is like a stone bound in a sling, with which a man will be likely to do hurt. To give honour to a fool is to put a sword in a madman's hand, with which we know not what mischief he may do, even to those that put it into his hand. 3. They are not fit to deliver wise sayings, nor should they undertake to handle any matter of weight, though they should be instructed concerning it, and be able to say something to it. Wise sayings, as a foolish man delivers them and applies them (in such a manner that one may know he does not rightly understand them), lose their excellency and usefulness: A parable in the mouth of fools ceases to be a parable, and becomes a jest. If a man who lives a wicked life, yet speaks religiously and takes God's covenant into his mouth, (1.) He does but shame himself and his profession: As the legs of the lame are not equal, by reason of which their going is unseemly, so unseemly is it for a fool to pretend to speak apophthegms, and give advice, and for a man to talk devoutly whose conversation is a constant contradiction to his talk and gives him the lie. His good words raise him up, but then his bad life takes him down, and so his legs are not equal. "A wise saying," (says bishop Patrick) "doth as ill become a fool as dancing doth a cripple; for, as his lameness never so much appears as when he would seem nimble, so the other's folly is never so ridiculous as when he would seem wise." As therefore it is best for a lame man to keep his seat, so it is best for a silly man, or a bad man, to hold his tongue. (2.) He does but do mischief with it to himself and others, as a drunkard does with a thorn, or any other sharp thing which he takes in his hand, with which he tears himself and those about him, because he knows not how to manage it. Those that talk well and do not live well, their good words will aggravate their own condemnation and others will be hardened by their inconsistency with themselves. Some give this sense of it: The sharpest saying, by which a sinner, one would think, should be pricked to the heart, makes no more impression upon a fool, no, though it come out of his own mouth, than the scratch of a thorn does upon the hand of a man when he is drunk, who then feels it not nor complains of it, ch. xxiii. 35.
