And the Lord called Samuel the third time. And he went to Eli and said, Here I am, for you did call me. Then Eli perceived that the Lord was calling the boy. So Eli said to Samuel, Go, lie down. And if He calls you, you shall say, Speak, Lord, for Your servant is listening. So Samuel went and lay down in his place. And the Lord came and stood and called as at other times, Samuel! Samuel! Then Samuel answered, Speak, Lord, for Your servant is listening.
