Love not sleep, lest thou come to poverty,.... Sleep is a very great natural blessing; it is a gift of God, what nature requires, and is desirable; it is to be loved, though not immoderately; it is sweet to a man, and what he should be thankful for; yet should not indulge himself in to the neglect of the proper business of life; nor to be used but at the proper time for it; for the eye is made for sight, and not for sleep only, as Aben Ezra observes, connecting the words with the preceding; and therefore should not be kept shut and inattentive to business, which must necessarily end in poverty and want; see Pro 6:9; and so spiritual sleep and slothfulness bring on a spiritual poverty in the souls of men, both as to the exercise of grace and the performance of duty; open thine eyes, and thou shall be satisfied with bread; that is, open thine eyes from sleep, awake and keep so, and be sedulous and industrious in the business of thy calling; so shalt thou have a sufficiency of food for thyself and family; see Pro 12:11. It may be applied to awaking out of sleep in a spiritual sense, and to a diligent attendance to duty and the use of means, whereby the souls of men come to be satisfied with the goodness of the Lord, and the fatness of his house; see Eph 5:14.
