1 Samuel 3:4, 6, 8, 10

Then the LORD called Samuel. Samuel answered, “Here I am.”

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.

The LORD came and stood there, calling as at the other times, “Samuel! Samuel!” Then Samuel said, “Speak, for your servant is listening.”
