15 The labor of fools wearies every one of them; for he doesn’t know how to go to the city.

16 Woe to you, land, when your king is a child,
and your princes eat in the morning! 17 Happy are you, land, when your king is the son of nobles,
and your princes eat in due season,
for strength, and not for drunkenness! 18 By slothfulness the roof sinks in;
and through idleness of the hands the house leaks. 19 A feast is made for laughter,
and wine makes the life glad;
and money is the answer for all things. 20 Don’t curse the king, no, not in your thoughts;
and don’t curse the rich in your bedchamber:
for a bird of the sky may carry your voice,
and that which has wings may tell the matter.

Matthew Henry's Commentary on Ecclesiastes 10:15-20

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.

Commentary on Ecclesiastes 10:16-20

(Read Ecclesiastes 10:16-20)

The happiness of a land depends on the character of its rulers. The people cannot be happy when their princes are childish, and lovers of pleasure. Slothfulness is of ill consequence both to private and public affairs. Money, of itself, will neither feed nor clothe, though it answers the occasions of this present life, as what is to be had, may generally be had for money. But the soul, as it is not redeemed, so it is not maintained with corruptible things, as silver and gold. God sees what men do, and hears what they say in secret; and, when he pleases, brings it to light by strange and unsuspected ways. If there be hazard in secret thoughts and whispers against earthly rulers, what must be the peril from every deed, word, or thought of rebellion against the King of kings, and Lord of lords! He seeth in secret. His ear is ever open. Sinner! curse not THIS KING in thy inmost thought. Your curses cannot affect Him; but his curse, coming down upon you, will sink you to the lowest hell.
