1 Samuel 2:28-29

28I chose your ancestor out of all the tribes of Israel to be my priest, to go up to my altar, to burn incense, and to wear an ephod in my presence. I also gave your ancestor’s family all the food offerings presented by the Israelites.

29Why do you scorn my sacrifice and offering that I prescribed for my dwelling? Why do you honor your sons more than me by fattening yourselves on the choice parts of every offering made by my people Israel?’
