1 Samuel 2:25-35

25 If a man sins against a man, God will mediate for him; but if a man sins against the LORD, who can intercede for him?" But they would not listen to the voice of their father; for it was the will of the LORD to slay them.
26 Now the boy Samuel continued to grow both in stature and in favor with the LORD and with men.
27 And there came a man of God to Eli, and said to him, "Thus the LORD has said, 'I revealed myself to the house of your father when they were in Egypt subject to the house of Pharaoh.
28 And I chose him out of all the tribes of Israel to be my priest, to go up to my altar, to burn incense, to wear an ephod before me; and I gave to the house of your father all my offerings by fire from the people of Israel.
29 Why then look with greedy eye at my sacrifices and my offerings which I commanded, and honor your sons above me by fattening yourselves upon the choicest parts of every offering of my people Israel?'
30 Therefore the LORD the God of Israel declares: 'I promised that your house and the house of your father should go in and out before me for ever'; but now the LORD declares: 'Far be it from me; for those who honor me I will honor, and those who despise me shall be lightly esteemed.
31 Behold, the days are coming, when I will cut off your strength and the strength of your father's house, so that there will not be an old man in your house.
32 Then in distress you will look with envious eye on all the prosperity which shall be bestowed upon Israel; and there shall not be an old man in your house for ever.
33 The man of you whom I shall not cut off from my altar shall be spared to weep out his eyes and grieve his heart; and all the increase of your house shall die by the sword of men.
34 And this which shall befall your two sons, Hophni and Phin'ehas, shall be the sign to you: both of them shall die on the same day.
35 And I will raise up for myself a faithful priest, who shall do according to what is in my heart and in my mind; and I will build him a sure house, and he shall go in and out before my anointed for ever.
