5 There is an evil which I have seen under the sun, as it were an error which proceedeth from the ruler: 6 folly is set in great dignity, and the rich sit in a low place. 7 I have seen servants upon horses, and princes walking like servants upon the earth. 8 He that diggeth a pit shall fall into it; and whoso breaketh through a wall, a serpent shall bite him. 9 Whoso heweth out stones shall be hurt therewith; [and] he that cleaveth wood is endangered thereby. 10 If the iron be blunt, and one do not whet the edge, then must he put to more strength: but wisdom is profitable to direct. 11 If the serpent bite before it is charmed, then is there no advantage in the charmer.
12 The words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself. 13 The beginning of the words of his mouth is foolishness; and the end of his talk is mischievous madness. 14 A fool also multiplieth words: [yet] man knoweth not what shall be; and that which shall be after him, who can tell him?

Commentary on Ecclesiastes 10:4-10
(Read Ecclesiastes 10:4-10)
Solomon appears to caution men not to seek redress in a hasty manner, nor to yield to pride and revenge. Do not, in a passion, quit thy post of duty; wait awhile, and thou wilt find that yielding pacifies great offences. Men are not preferred according to their merit. And those are often most forward to offer help, who are least aware of the difficulties, or the consequences. The same remark is applied to the church, or the body of Christ, that all the members should have the same care one for another.
Commentary on Ecclesiastes 10:11-15
(Read Ecclesiastes 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, Isaiah 25:8. But sinful folly makes men miss that only way to happiness.
