1 Samuel 2:13-17

131And this was the custom of the priests with the people: when anyone was offering a sacrifice, the priest’s servant would come while the meat was cooking, with a three-pronged fork in his hand. 14And he would thrust it into the pan, or kettle, or caldron, or pot; everything that the fork brought up, the priest would take for himself. They did so in Shiloh to all the Israelites who came there. 15Also, before 2they 3burned 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 cooked meat from you, only raw.” 16And if the man said to him, “They must 4burn the fat 5first, then take as much as 6you desire,” then he would say, “No, but you must give it to me now; and if not, I am taking it by force!” 17And so the sin of the young men was very great before the Lord, for the men 7treated the offering of the Lord disrespectfully.
