1 Samuel 3:8-9

New International Version

⁸ 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. ⁹ So Eli told Samuel, “Go and lie down, and if he calls you, say, ‘Speak, Lord, for your servant is listening.’” So Samuel went and lay down in his place.
