7 The term עִנְיַן (’inyan) means “business; affair; task; occupation” ( עִנְיָן; 775 עִנְיָן). nuances עִנְיַן בְּרֹב (bérov ̑inyan) as “excessive activity” ( עִנְיָן). Here, it is used as a metonymy of cause (i.e., tasks) for effect (i.e., cares). The term is nuanced variously: (1) literal sense: “business” (, , , , ) and “effort” (), and (2) metonymical: “cares” (, , ), “concerns” (, ), “worries” () and “brooding” (). The mistakenly related עִנְיַן to the root II עָנַה (’anah) “to afflict,” and rendered it as πειρασμοῦ (peirasmou, “trial”).
8 The juxtaposition of the two lines joined by vav (“just as … so …”) suggests a comparison ( 253 ו 1.j); see R. J. Williams, Hebrew Syntax, 71, §437.
9 Heb “voice.” The Hebrew term קוֹל (qol, “voice”) is used as a metonymy of cause (i.e., voice) for the contents (i.e., the thing said), e.g., Gen 3:17; 4:23; Exod 3:18; 4:1, 9; Deut 1:45; 21:18, 20; 1 Sam 2:25; 8:7, 9; 2 Sam 12:18); see קוֹל 4.b; 877 קוֹל 3.a; also E. W. Bullinger, Figures of Speech, . Contextually, this refers to a rash vow made by a fool who made a mistake in making it because he is unable to fulfill it.
10 The word “occurs” does not appear in the Hebrew text, but is supplied in the translation for clarity.

In other versions

For a dream comes with much business, and a fool’s voice with many words.

A dream comes when there are many cares,

and many words mark the speech of a fool.

Just as dreams accompany much labor, so also a fool’s voice comes with many words.

Too much activity gives you restless dreams; too many words make you a fool.

For a dream comes with many cares,

and the voice of a fool with many words.

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