1 Samuel 2:11-15

Then Elkanah went to his home at Ramah. But the boy ministered to the LORD before Eli the priest. Now the sons of Eli were worthless men; they did not know the LORD and the custom of the priests with the people. When any man was offering a sacrifice, the priest’s servant would come while the meat was boiling, with a three-pronged fork in his hand. Then he would thrust it into the pan, or kettle, or caldron, or pot; all that the fork brought up the priest would take for himself. Thus they did in Shiloh to all the Israelites who came there. Also, before they burned the fat, the priest’s servant would come and say to the man who was sacrificing, “Give the priest meat for roasting, as he will not take boiled meat from you, only raw.”
