For a dream cometh through the multitude of business; and a fool's voice is known by multitude of words.

For a dream cometh with a multitude of business, and a fool's voice with a multitude of words.

Dreams follow many cares: and in many words shall be found folly.

For the dream hath come by abundance of business, and the voice of a fool by abundance of words.

As a dream comes from much business, so the voice of a foolish man comes with words in great number.

Dreams follow many worries, and in many words foolishness will be found.

For a dream cometh - That is, as dreams are generally the effect of the business in which we have been engaged during the day; so a multitude of words evidence the feeble workings of the foolish heart.

For a dream cometh through the multitude of business,.... Or, "for as a dream" (q), so Aben Ezra; as that comes through a multiplicity of business in the daytime, in which the mind has been busied, and the body employed; and this brings on dreams in the night season, which are confused and incoherent; sometimes the fancy is employed about one thing, and sometimes another, and all unprofitable and useless, as well as vain and foolish;
and a fool's voice is known by multitude of words; either his voice in conversation, for a fool is full of words, and pours out his foolishness in a large profusion of them; or his voice in prayer, being like a man's dream, confused, incoherent, and rambling. The supplement, "is known", may be left out.
(q) "ut prodit somnium", Junius & Tremellius; "nam ut venit", Piscator; "quia sicut venit", Mercerus, Ramabachius, so Broughton.

As much "business," engrossing the mind, gives birth to incoherent "dreams," so many words, uttered inconsiderately in prayer, give birth to and betray "a fool's speech" (Ecclesiastes 10:14), [HOLDEN and WEISS]. But Ecclesiastes 5:7 implies that the "dream" is not a comparison, but the vain thoughts of the fool (sinner, Psalm 73:20), arising from multiplicity of (worldly) "business." His "dream" is that God hears him for his much speaking (Matthew 6:7), independently of the frame of mind [English Version and MAURER].
fool's voice--answers to "dream" in the parallel; it comes by the many "words" flowing from the fool's "dream."

A dream - When men are oppressed with business in the day, they dream of it in the night. Is known - It discovers the man to be a foolish, and rash, and inconsiderate man. Of words - Either in prayer, or in vowing, by making many rash vows, of which he speaks Ecclesiastes 5:4-6, and then returns to the mention of multitude of dreams and many words, Ecclesiastes 5:7, which verse may be a comment upon this, and which makes it probable that both that and this verse are to be understood of vows rather than of prayers.
