1 Samuel 2:22-25, 29

Now Eli was very old, and heard all that his sons did unto all Israel; and how they lay with the women that assembled at the door of the tabernacle of the congregation. And he said unto them, Why do ye such things? for I hear of your evil dealings by all this people. Nay, my sons; for it is no good report that I hear: ye make the LORD's people to transgress. If one man sin against another, the judge shall judge him: but if a man sin against the LORD, who shall intreat for him? Notwithstanding they hearkened not unto the voice of their father, because the LORD would slay them.

Wherefore kick ye at my sacrifice and at mine offering, which I have commanded in my habitation; and honourest thy sons above me, to make yourselves fat with the chiefest of all the offerings of Israel my people?
