The beginning of the words of his mouth is foolishness,.... As soon as ever he opens his mouth, he betrays his folly; the first word he speaks is a foolish one; or it is from the abundant folly in his heart that he speaks, which is the source and spring of all his foolish talk;

and the end of his talk is mischievous madness; to himself and others; as he goes on, he appears more and more foolish, and yet more confident of his own wisdom; and is resolutely set on having his own way and will; grows warm, and is violently hot, to have his own words regarded; and, if contradicted, is like a madman, scattering arrows, firebrands, and death; his talk from first to last is a circle of folly; and, though it begins with something weak, and may seem innocent, yet it ends and issues in wickedness and madness, in rage and wrath, in oaths and curses.

"The beginning of the words of his mouth is foolishness; and the end of his mouth is mischievous madness." From folly (absurdity) the words which are heard from a fool's mouth rise to madness, which is compounded of presumption, wantonness, and frenzy, and which, in itself a symptom of mental and moral depravity, brings as its consequence destruction on himself (Proverbs 18:17). The adjective רעה is as in רע חלי, which interchanges with רעה חו Ecclesiastes 6:2; Ecclesiastes 5:12, etc. The end of his mouth, viz., of his speaking, is equals the end of the words of his mouth, viz., the end which they at last reach. Instead of holeloth, there is here, with the adj. following, holeluth, with the usual ending of abstracta. The following proverb says how the words of the fool move between these two poles of folly and wicked madness: he speaks much, and as if he knew all things.

The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.

his talk: Heb. his mouth

13. Illustrating the folly and injuriousness of the fool's words; last clause of Ec 10:12.

10:11-15 There is a practice in the East, of charming serpents by music. The babbler's tongue is an unruly evil, full of deadly poison; and contradiction only makes it the more violent. We must find the way to keep him gentle. But by rash, unprincipled, or slanderous talk, he brings open or secret vengeance upon himself. Would we duly consider our own ignorance as to future events, it would cut off many idle words which we foolishly multiply. Fools toil a great deal to no purpose. They do not understand the plainest things, such as the entrance into a great city. But it is the excellency of the way to the heavenly city, that it is a high-way, in which the simplest wayfaring men shall not err, Isa 25:8. But sinful folly makes men miss that only way to happiness.
