1 Samuel 2:15-17

15Also, 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.”

16And if the man said to him, “They should really burn the fat first; then you may take as much as your heart desires,” he would then answer him, “No, but you must give it now; and if not, I will take it by force.”

17Therefore the sin of the young men was very great before the Lord, for men abhorred the offering of the Lord.
