1 Samuel 3:12-14

3:12 On that day I will carry out against Eli everything that I spoke about his house – from start to finish! 3:13 You should tell him that I am about to judge his house forever because of the sin that he knew about. For his sons were cursing God, and he did not rebuke them. 3:14 Therefore I swore an oath to the house of Eli, ‘The sin of the house of Eli can never be forgiven by sacrifice or by grain offering.’”
