1 Samuel 3:2-6

And it came to pass at that time, when Eli was laid down in his place, and his eyes began to wax dim, that he could not see;

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;

That the LORD called Samuel: and he answered, Here am I.

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.

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.
