1 Samuel 3:4-6, 8, 16

Then the LORD called Samuel. Samuel answered, “Here I am.” And he ran to Eli and said, “Here I am; you called me.” But Eli said, “I did not call; go back and lie down.” So he went and lay down. Again the LORD called, “Samuel!” And Samuel got up and went to Eli and said, “Here I am; you called me.” “My son,” Eli said, “I did not call; go back and lie down.”

A third time the LORD called, “Samuel!” And Samuel got up and went to Eli and said, “Here I am; you called me.” Then Eli realized that the LORD was calling the boy.

but Eli called him and said, “Samuel, my son.” Samuel answered, “Here I am.”
