1 Samuel 2:27-30

Then a man of God (prophet) came to Eli and said to him, “Thus says the LORD: ‘Did I not plainly reveal Myself to the house of your father (ancestor) when they were in Egypt in bondage to Pharaoh’s house? Moreover, I selected 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 [from then on] I gave to the house of your father all the fire offerings of the sons of Israel. Why then do you kick at (despise) My sacrifice and My offering which I commanded in My dwelling place, and honor your sons more than Me, by fattening yourselves with the choicest part of every offering of My people Israel?’ Therefore the LORD God of Israel declares, ‘I did indeed say that your house and that of [Aaron] your father would walk [in priestly service] before Me forever.’ But now the LORD declares, ‘Far be it from Me—for those who honor Me I will honor, and those who despise Me will be insignificant and contemptible.
