When men's minds are distracted and oppressed with too much business in the day, they dream of it in the night. A fool's voice is known; it discovers the man to be a foolish, and rash, and inconsiderate man. By multitude of words; either,
1. In prayer. Or,
2. In vowing, i.e. by making many rash vows, of which he speaks in 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.
