For a dream cometh through the multitude of business
Or, "for as a dream" F17, 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.
F17 (ab yk) "ut prodit somnium", Junius & Tremellius; "nam ut venit", Piscator; "quia sicut venit", Mercerus, Ramabachius, so Broughton.
