I Samuel 3:8-15

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. Now the LORD came and stood and called as at other times, “Samuel! Samuel!” And Samuel answered, “Speak, for Your servant hears.” Then the LORD said to Samuel: “Behold, I will do something in Israel at which both ears of everyone who hears it will tingle. In that day I will perform against Eli all that I have spoken concerning his house, from beginning to end. For I have told him that I will judge his house forever for the iniquity which he knows, because his sons made themselves vile, and he did not restrain them. And therefore I have sworn to the house of Eli that the iniquity of Eli’s house shall not be atoned for by sacrifice or offering forever.” So Samuel lay down until morning, and opened the doors of the house of the LORD. And Samuel was afraid to tell Eli the vision.
