11 Then the Lord said to Samuel, "See, I am about to do something in Israel that will make both ears of anyone who hears of it tingle. 12 On that day I will fulfill against Eli all that I have spoken concerning his house, from beginning to end. 13 For I have told him that I am about to punish his house forever, for the iniquity that he knew, because his sons were blaspheming God, and he did not restrain them. 14 Therefore I swear to the house of Eli that the iniquity of Eli's house shall not be expiated by sacrifice or offering forever." 15 Samuel lay there until morning; then he opened the doors of the house of the Lord. Samuel was afraid to tell the vision to Eli. 16 But Eli called Samuel and said, "Samuel, my son." He said, "Here I am." 17 Eli said, "What was it that he told you? Do not hide it from me. May God do so to you and more also, if you hide anything from me of all that he told you." 18 So Samuel told him everything and hid nothing from him. Then he said, "It is the Lord; let him do what seems good to him."

Commentary on 1 Samuel 3:11-18
(Read 1 Samuel 3:11-18)
What a great deal of guilt and corruption is there in us, concerning which we may say, It is the iniquity which our own heart knoweth; we are conscious to ourselves of it! Those who do not restrain the sins of others, when it is in their power to do it, make themselves partakers of the guilt, and will be charged as joining in it. In his remarkable answer to this awful sentence, Eli acknowledged that the Lord had a right to do as he saw good, being assured that he would do nothing wrong. The meekness, patience, and humility contained in those words, show that he was truly repentant; he accepted the punishment of his sin.
