1st Samuel 3:6

3 and the lamp of God was not yet gone out, and Samuel was laid down [to sleep], in the temple of Jehovah, where the ark of God was;

4 that Jehovah called Samuel; and he said, 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 Jehovah called yet again, Samuel. And Samuel arose and went to Eli, and said, Here am I; for thou calledst me. And he answered, I called not, my son; lie down again.

7 Now Samuel did not yet know Jehovah, neither was the word of Jehovah yet revealed unto him.

8 And Jehovah called Samuel again the third time. And he arose and went to Eli, and said, Here am I; for thou calledst me. And Eli perceived that Jehovah 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, Jehovah; for thy servant heareth. So Samuel went and lay down in his place.
