1 Samuel 3:8-9

English Standard Version

⁸ 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. ⁹ Therefore Eli said to Samuel, “Go, lie down, and if he calls you, you shall say, ‘Speak, Lord, for your servant hears.’” So Samuel went and lay down in his place.
