I Samuel 2:11-15

Then Elkanah went to his house at Ramah. But the child ministered to the LORD before Eli the priest. Now the sons of Eli were corrupt; they did not know the LORD. And the priests’ custom with the people was that when any man offered a sacrifice, the priest’s servant would come with a three-pronged fleshhook in his hand while the meat was boiling. Then he would thrust it into the pan, or kettle, or caldron, or pot; and the priest would take for himself all that the fleshhook brought up. So 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 sacrificed, “Give meat for roasting to the priest, for he will not take boiled meat from you, but raw.”
