For in the multitude of dreams ... (there are) ... vanities, ... - (Note, Ecclesiastes 5:3.) God's service, which ought to be our chief good, becomes by "dreams" (foolish fancies as to God's requirements of us in worship) and random "words," positive "vanity." The remedy is, "Fear God" (Ecclesiastes 12:13), then thou wilt speak and vow nothing which thou dost not sincerely mean.
