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 (Pro 26:6): 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 (Pro 26:1), 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, Pro 23:35.

As he that bindeth a stone in a sling,.... That so fastens it to it that it cannot be slung out of it, it becomes useless and does not answer the end for which it is put there; or that places it there that it may be cast out, and is cast out, and so is thrown away, and of no more use; or that puts a precious stone, so some interpret it, in a heap of common stones, even in such a heap as is used at the stoning of malefactors; or increases the heap of stones on such, which the more exposes them, and the greater reproach they are loaded with; so the more a fool is praised, it does but bring to mind his folly, and issues in his greater disgrace, so Gussetius (o): or rather it has respect to a precious stone put in such a heap of stones, as Luther; or else, according to Schultens, to such an one put into a heap of sepulchral stones; or, as Aben Ezra, that binds up a stone, a common stone, in purple, which to do is ridiculous, so R. Joseph Kimchi; the Vulgate Latin version renders it,

"as he that casts a stone to Mercury's heap;''

a Heathen deity, called by the eastern people Mertholin and Margenah (p), which last is near the same with the Hebrew word here used; whose statue was set up where two or more ways met, to direct travellers; and who therefore out of respect to the deity, and to show gratitude to him, used to cast a stone to the heap for the support of it; and which stones, set up in such doubtful places, were dedicated to him, and were called after his name (q); and not only travellers did this in honour of the deity, and to make his statue more manifest (r), but also for profit, to clear the way from stones; and this custom obtained with the Indians, Arabs, Saracens, and now does with the Mahometans (s): and such heaps of stones were also placed in cities, and at the doors of houses, in honour of Mercury, and were called from him Hermae (t); these stones were also erected for borders of countries (u). But it is not probable that this custom obtained in Solomon's time; and yet some Jewish writers interpret it to this sense, as if he that gives honour to a fool is like him that casts a stone to Mercury; and Jarchi in the text observes it as the sense of some of their Rabbins,

"that he that teacheth the law to a disciple that is not fit, is as he that casts a stone to Mercury;''

and to cast a stone to Mercury is with them the same as to commit idolatry (w); but either of the former senses is best;

so is he that giveth honour to a fool; it is all thrown away and lost, as a stone out of a sling; or as unseemly as to put a precious stone among a heap of stones, or a common stone in purple; See Gill on Pro 26:1.

A stone, bound in a sling, is useless; so honor, conferred on a fool, is thrown away.
