“Speak Lord, For Your Servant Hears,” Samuel 1..

Now Hannah spoke in her heart; only her lips moved, but her voice was not heard. Therefore Eli thought she was drunk. So Eli said to her, “How long will you be drunk? Put your wine away from you!” But Hannah answered and said, “No, my lord, I am a woman of sorrowful spirit. I have drunk neither wine nor intoxicating drink, but have poured out my soul before the Lord. Do not consider your maidservant a wicked woman, for out of the abundance of my complaint and grief I have spoken until now.” Then Eli answered and said, “Go in peace, and the God of Israel grant your petition which you have asked of Him.” So it came to pass in the process of time that Hannah conceived and bore a son, and called his name Samuel, saying, “Because I have asked for him from the Lord.” Now the boy Samuel ministered to the Lord before Eli. And the word of the Lord was rare in those days; there was no widespread revelation. ASamuel was lying down, that the Lord called Samuel. And he answered, “Here I am!” So he ran to Eli and said, “Here I am, for you called me.” And he said, “I did not call; lie down again.” And he went and lay down. Then the Lord called yet again, “Samuel!” So Samuel arose and went to Eli, and said, “Here I am, for you called me.” He answered, “I did not call, my son; lie down again.” (Now Samuel did not yet know the Lord, nor was the word of the Lord yet revealed to him.) And the Lord called Samuel again the third time. So he arose and went to Eli, and said, “Here I am, for you did call me.” Then Eli perceived that the Lord had called the boy. Therefore Eli said to Samuel, “Go, lie down; and it shall be, if He calls you, that you must say, ‘Speak, Lord, for Your servant hears.’ ” So Samuel went and lay down in his place.
