1 Samuel 3:4-6, 8, 16

Then the LORD called Samuel, and he said, “Here I am!” and ran to Eli and said, “Here I am, for you called me.” But he said, “I did not call; lie down again.” So he went and lay down. And the LORD called again, “Samuel!” and Samuel arose and went to Eli and said, “Here I am, for you called me.” But he said, “I did not call, my son; lie down again.”

And the LORD called Samuel again the third time. And he arose and went to Eli and said, “Here I am, for you called me.” Then Eli perceived that the LORD was calling the boy.

But Eli called Samuel and said, “Samuel, my son.” And he said, “Here I am.”
