1 Samuel 3:5

And he ran unto Eli and said, Here am I; for thou calledst me. That was the conclusion which he naturally drew, and his faithful willingness took him to the room of Eli as quickly as he could get there a fine example to many a young man of our days. And he, Eli, said, I called not; lie down again, evidently supposing that Samuel had merely dreamed he was being called. And he went and lay down.
