Yet a little sleep, a little slumber, {c} a little folding of the hands to sleep:

(c) He expresses the nature of the sluggards, who though they sleep long, yet never have enough, but always seek opportunity for more.

Matthew Henry's Concise Commentary

6:6-11 Diligence in business is every man's wisdom and duty; not so much that he may attain worldly wealth, as that he may not be a burden to others, or a scandal to the church. The ants are more diligent than slothful men. We may learn wisdom from the meanest insects, and be shamed by them. Habits of indolence and indulgence grow upon people. Thus life runs to waste; and poverty, though at first at a distance, gradually draws near, like a traveller; and when it arrives, is like an armed man, too strong to be resisted. All this may be applied to the concerns of our souls. How many love their sleep of sin, and their dreams of worldly happiness! Shall we not seek to awaken such? Shall we not give diligence to secure our own salvation?
