A. Don't oversleep when you should be working:

PRO 6:9. How long wilt thou sleep, O sluggard? when wilt thou arise out of thy sleep?

PRO 6:10. Yet a little sleep, a little slumber, a little folding of the hands to sleep:

PRO 6:11. So shall thy poverty come as one that travelleth, and thy want as an armed man.

PRO 24:33. Yet a little sleep, a little slumber, a little folding of the hands to sleep:

PRO 24:34. So shall thy poverty come as one that travelleth; and thy want as an armed man.

PRO 10:5. He that gathereth in summer is a wise son: but he that sleepeth in harvest is a son that causeth shame.

PRO 20:13. Love not sleep, lest thou come to poverty; open thine eyes, and thou shalt be satisfied with bread.

PRO 26:14. As the door turneth upon his hinges, so doth the slothful upon his bed.

B. Times to rise & pray:

JON 1:4. But the LORD sent out a great wind into the sea, and there was a mighty tempest in the sea, so that the ship was like to be broken.

JON 1:5. Then the mariners were afraid, and cried every man unto his god, and cast forth the wares that were in the ship into the sea, to lighten it of them. But Jonah was gone down into the sides of the ship; and he lay, and was fast asleep.

JON 1:6. So the shipmaster came to him, and said unto him, What meanest thou, O sleeper? arise, call upon thy God, if so be that God will think upon us, that we perish not.

MAR 14:37. And he cometh, and findeth them sleeping, and saith unto Peter, Simon, sleepest thou? couldest not thou watch one hour?

MAR 14:38. Watch ye and pray, lest ye enter into temptation. The spirit truly is ready, but the flesh is weak.

MAR 14:39. And again he went away, and prayed, and spake the same words.

MAR 14:40. And when he returned, he found them asleep again, (for their eyes were heavy,) neither wist they what to answer him.

LUK 22:46. And said unto them, Why sleep ye? rise and pray, lest ye enter into temptation.

C. When something important needs to be done first:

PSA 132:3. Surely I will not come into the tabernacle of my house, nor go up into my bed;

PSA 132:4. I will not give sleep to mine eyes, or slumber to mine eyelids,

PSA 132:5. Until I find out a place for the LORD, an habitation for the mighty God of Jacob.

PRO 6:1. My son, if thou be surety for thy friend, if thou hast stricken thy hand with a stranger,

PRO 6:2. Thou art snared with the words of thy mouth, thou art taken with the words of thy mouth.

PRO 6:3. Do this now, my son, and deliver thyself, when thou art come into the hand of thy friend; go, humble thyself, and make sure thy friend.

PRO 6:4. Give not sleep to thine eyes, nor slumber to thine eyelids.

D. Oversleeping can be caused by laziness or unconcern for others:

PRO 19:15. Slothfulness casteth into a deep sleep; and an idle soul shall suffer hunger.

ISA 56:10. His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber.

ISA 56:11. Yea, they are greedy dogs which can never have enough, and they are shepherds that cannot understand: they all look to their own way, every one for his gain, from his quarter.

E. Sleep can symbolise spiritual insensitivity:

ROM 13:11. And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.

ROM 13:12. The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.

1TH 5:6. Therefore let us not sleep, as do others; but let us watch and be sober.

1TH 5:7. For they that sleep sleep in the night; and they that be drunken are drunken in the night.
