1 Samuel 2:28-29

28Did I not choose him out of all the tribes of Israel to be My priest, to offer upon My altar, to burn incense, and to wear an ephod before Me? And did I not give to the house of your father all the offerings of the children of Israel made by fire?

29Why do you kick at My sacrifice and My offering which I have commanded in My dwelling place, and honor your sons more than Me, to make yourselves fat with the best of all the offerings of Israel My people?’
