101 Dead flies cause the ointment of the apothecary to stink [and] ferment; [so] a little folly is weightier than wisdom [and] honour. 2 The heart of a wise [man] is at his right hand; but a fool's heart at his left. 3 Yea also, when he that is a fool walketh by the way, his sense faileth [him], and he saith to every one [that] he is a fool.
Matthew Henry's Commentary on Ecclesiastes 10:1-3
Commentary on Ecclesiastes 10:1-3
(Read Ecclesiastes 10:1-3)
Those especially who make a profession of religion, should keep from all appearances of evil. A wise man has great advantage over a fool, who is always at a loss when he has anything to do. Sin is the reproach of sinners, wherever they go, and shows their folly.
