1 Samuel 3:16-18

Then Eli called Samuel, and said— Either that he might not afflict Eli, or displease God, Samuel feared to tell this unhappy father what had been revealed to him. But Eli, naturally distressed and uneasy, presses him earnestly to conceal nothing from him: he adjures him by a solemn imprecation, God do so to thee, &c. which obliged Samuel to satisfy his desire. The manner in which Eli received this terrible denunciation does great credit to his character. He acknowledged the greatness of his fault, and humbly resigned himself to the will of God.
