1 Samuel 3:3-9 King James Version (KJV)
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;
4 That the Lord called Samuel: and he answered, Here am I.
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.
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.
7 Now Samuel did not yet know the Lord, neither was the word of the Lord yet revealed unto him.
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.
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.
