1 Samuel 2:27-31

One day a man of God came to Eli and gave him this message from the LORD: “I revealed myself to your ancestors when they were Pharaoh’s slaves in Egypt. I chose your ancestor Aaron from among all the tribes of Israel to be my priest, to offer sacrifices on my altar, to burn incense, and to wear the priestly vest as he served me. And I assigned the sacrificial offerings to you priests. So why do you scorn my sacrifices and offerings? Why do you give your sons more honor than you give me—for you and they have become fat from the best offerings of my people Israel! “Therefore, the LORD, the God of Israel, says: I promised that your branch of the tribe of Levi would always be my priests. But I will honor those who honor me, and I will despise those who think lightly of me. The time is coming when I will put an end to your family, so it will no longer serve as my priests. All the members of your family will die before their time. None will reach old age.
