A. When the Lord wants to speak to you:

1SAM 3:3. And ere the lamp of God went out in the temple of the LORD, where the ark of God was, and Samuel was laid down to sleep;

1SAM 3:4. That the LORD called Samuel: and he answered, Here am I.

1SAM 3:5. And he ran unto Eli, and said, Here am I; for thou calledst me. And he said, I called not; lie down again. And he went and lay down.

1SAM 3:6. And the LORD called yet again, Samuel. And Samuel arose and went to Eli, and said, Here am I; for thou didst call me. And he answered, I called not, my son; lie down again.

1SAM 3:7. Now Samuel did not yet know the LORD, neither was the word of the LORD yet revealed unto him.

1SAM 3:8. And the LORD called Samuel again the third time. And he arose and went to Eli, and said, Here am I; for thou didst call me. And Eli perceived that the LORD had called the child.

1SAM 3:9. Therefore Eli said unto Samuel, Go, lie down: and it shall be, if he call thee, that thou shalt say, Speak, LORD; for thy servant heareth. So Samuel went and lay down in his place.

1SAM 3:10. And the LORD came, and stood, and called as at other times, Samuel, Samuel. Then Samuel answered, Speak; for thy servant heareth.

JOB 4:12. Now a thing was secretly brought to me, and mine ear received a little thereof.

JOB 4:13. In thoughts from the visions of the night, when deep sleep falleth on men,

JOB 4:14. Fear came upon me, and trembling, which made all my bones to shake.

JOB 4:15. Then a spirit passed before my face; the hair of my flesh stood up:

JOB 4:16. It stood still, but I could not discern the form thereof: an image was before mine eyes, there was silence, and I heard a voice, saying,

JOB 4:17. Shall mortal man be more just than God? shall a man be more pure than his maker?

B. Sometimes God allows it to work out His will:

EST 6:1-3. On that night could not the king (Ahasuerus) sleep....

C. When worried or troubled:

PSA 77:3. I remembered God, and was troubled: I complained, and my spirit was overwhelmed. Selah.

PSA 77:4. Thou holdest mine eyes waking: I am so troubled that I cannot speak.

ECC 2:23. For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.

ECC 5:12. The sleep of a labouring man is sweet, whether he eat little or much: but the abundance of the rich will not suffer him to sleep.

DAN 6:14. Then the king, when he heard these words, was sore displeased with himself, and set his heart on Daniel to deliver him: and he laboured till the going down of the sun to deliver him.

DAN 6:15. Then these men assembled unto the king, and said unto the king, Know, O king, that the law of the Medes and Persians is, That no decree nor statute which the king establisheth may be changed.

DAN 6:16. Then the king commanded, and they brought Daniel, and cast him into the den of lions. Now the king spake and said unto Daniel, Thy God whom thou servest continually, he will deliver thee.

DAN 6:17. And a stone was brought, and laid upon the mouth of the den; and the king sealed it with his own signet, and with the signet of his lords; that the purpose might not be changed concerning Daniel.

DAN 6:18. Then the king went to his palace, and passed the night fasting: neither were instruments of musick brought before him: and his sleep went from him.

PSA 6:6. I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.

D. Because of unusual dreams:

DAN 2:1. And in the second year of the reign of Nebuchadnezzar Nebuchadnezzar dreamed dreams, wherewith his spirit was troubled, and his sleep brake from him.

JOB 7:13. When I say, My bed shall comfort me, my couch shall ease my complaints;

JOB 7:14. Then thou scarest me with dreams, and terrifiest me through visions:

E. When God is testing you as He did Job:

JOB 7:3. So am I made to possess months of vanity, and wearisome nights are appointed to me.

JOB 7:4. When I lie down, I say, When shall I arise, and the night be gone? and I am full of tossings to and fro unto the dawning of the day.

F. Punishment for disobeying God:

DEU 28:58. If thou wilt not observe to do all the words of this law that are written in this book, that thou mayest fear this glorious and fearful name, THE LORD THY GOD;

DEU 28:66. And thy life shall hang in doubt before thee; and thou shalt fear day and night, and shalt have none assurance of thy life:

DEU 28:67. In the morning thou shalt say, Would God it were even! and at even thou shalt say, Would God it were morning! for the fear of thine heart wherewith thou shalt fear, and for the sight of thine eyes which thou shalt see.

G. Be considerate of those who are sleeping:

PRO 27:14. He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.
