1 Samuel 2:15-17

15But even before the fat was burned, the priest’s servant would come and say to the person who was sacrificing, “Give the priest some meat to roast; he won’t accept boiled meat from you, but only raw.”

16If the person said to him, “Let the fat be burned first, and then take whatever you want,” the servant would answer, “No, hand it over now; if you don’t, I’ll take it by force.”

17This sin of the young men was very great in the LORD ’s sight, for they Dead Sea Scrolls and Septuagint; Masoretic Text people were treating the LORD ’s offering with contempt.
