1 Samuel 2:28-29
2:28 I 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.
2:29 Why 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.’
1 Samuel 6:15
6:15 The Levites took down the ark of the Lord and the chest that was with it, which contained the gold objects. They placed them near the big stone. At that time the people of Beth Shemesh offered burnt offerings and made sacrifices to the Lord.
