1 Samuel 2:28-29

28I chose your ancestor from all the tribes of Israel to be my priest, to offer sacrifice on my altar, to burn incense, and to bear the ephod before me. I gave to your ancestor’s house all the fire offerings made by the Israelites.

29Why are you scorning my sacrifice and my offering that I commanded for my dwelling place? You have honored your sons more than you have me by having made yourselves fat from the best parts of all the offerings of my people Israel.’
