1 Samuel 3:5

and ran to Eli, and said, Here I am, for thou didst call me. And he said, I did not call thee. Return, and go to sleep. So he returned and went to sleep. And the Lord again called Samuel! Samuel! Whereupon he went to Eli, a second time, and said, Here I am; for thou didst call me. And he said I did not call thee, Return, and go to sleep.
