1 Samuel 2:15-16

15Even before they burned the fat, the kohen’s servant would come and say to the one offering sacrifice, “Give the kohen meat for roasting, since he will not accept boiled meat from you—only raw.”

16If the man said to him, “Let them first burn the fat up as smoke, and then take as much as you desire,” he would reply, “No! But you must give it now—otherwise, I will take it by force.”
