In these verses Solomon shows,

I.What great need wise men have to take heed of being guilty of any instance of folly; for a little folly is a great blemish to him that is in reputation for wisdom and honour, and is as hurtful to his good name as dead flies are to a sweet perfume, not only spoiling the sweetness of it, but making it to send forth a stinking savour. Note, 1. True wisdom is true honour, and will gain a man a reputation, which is like a box of precious ointment, pleasing and very valuable. 2. The reputation that is got with difficulty, and by a great deal of wisdom, may be easily lost, and by a little folly, because envy fastens upon eminency, and makes the worst of the mistakes and miscarriages of those who are cried up for wisdom, and improves them to their disadvantage; so that the folly which in another would not be taken notice of in them is severely censured. Those who make a great profession of religion have need to walk very circumspectly, to abstain from all appearances of evil, and approaches towards it, because many eyes are upon them, that watch for their halting; their character is soon sullied, and they have a great deal of reputation to lose.

II.What a deal of advantage a wise man has above a fool in the management of business (Ecc 10:2): A wise man's heart is at his right hand, so that he goes about his business with dexterity, turns his hand readily to it, and goes through it with despatch; his counsel and courage are ready to him, whenever he has occasion for them. But a fool's heart is at his left hand; it is always to seek when he has any thing to do that is of importance, and therefore he goes awkwardly about it, like a man that is left-handed; he is soon at a loss and at his wits' end.

III.How apt fools are at every turn to proclaim their own folly, and expose themselves; he that is either witless or graceless, either silly or wicked, if he be ever so little from under the check, and left to himself, if he but walk by the way, soon shows what he is; his wisdom fails him, and, by some impropriety or other, he says to every one he meets that he is a fool (Ecc 10:3), that is, he discovers his folly as plainly as if he had told them so. He cannot conceal it, and he is not ashamed of it. Sin is the reproach of sinners wherever they go.

Dead flies cause the ointment of the apothecary to send forth a stinking savour,.... Such, as Jarchi observes, are in the winter season, which are weak and near to death, and get into precious ointment, prepared after the best manner, where they die, and corrupt and spoil it: or, "flies of deaths" (m); deadly ones, which have something in their nature poisonous and pernicious; which, when they light upon the most sweet and savoury ointment, give it an ill smell;

so doth a little folly him that is in reputation for wisdom and honour; a good name is like precious ointment, valuable and fragrant; sin, which is folly, is like a dead fly; not only light and mean, and base and worthless, but hurtful and pernicious, deadly, and the cause of death; and what may seem little, a peccadillo, or, however, one single act of sin, may injure the character of a wise and honourable man, and greatly expose him to shame and contempt, and cause him to stink in the nostrils of men, Gen 36:20; and to be reproached by men, and religion and government to be reproached for his sake. Thus the affair of Bathsheba and Uriah, what a slur did it bring on the character of David, so famous for wisdom and honour, for religion and piety? and the idolatry of Solomon, the wisest of men; Jehoshaphat, that good king, entering into affinity with Ahab; and pious Josiah going to war with the king of Egypt, contrary to the word of the Lord; with many other instances. This teaches how careful men eminent for gifts and grace should be of their words and actions; since the least thing amiss in them is easily discerned, and soon taken notice of, as the least speck in a diamond, or spot in fine linen, clean and white; and there are wicked and envious persons enough watching for their halting, glad to have an occasion against them, and improve everything to the uttermost: this is a caution to wise magistrates, honourable ministers of the word, and eminent professors more especially. The Targum is,

"evil concupiscence, which dwells at the gates of the heart, is as a fly, and is the cause of death in the world; and corrupts a good name, which was before like to anointing oil, perfumed with spices:''

and to the same purpose the Midrash. One of the names of Satan is Beelzebub, the lord of a fly; who, by his temptations, solicits to sin and folly, which produce the effect here mentioned, and therefore to be shunned as a deadly fly in the ointment, Mat 12:24. Gussetius (n) renders it,

"that which is precious and worthy of honour "proceeds" from wisdom; and folly "comes" from glory, "worldly glory", in a little time.''
