1 Samuel 2:12-14

12 But the sons of Eli [were] sons of Belial; they did not know the LORD.

13 [It was] the priests' custom with the people [that] when anyone offered a sacrifice, the priest's servant would come, while the flesh was being boiled, with a fleshhook of three teeth in his hand;

14 and he would strike [it] into the pan or kettle or caldron or pot, and all that the fleshhook brought up, the priest took for himself. Thus would they do in Shiloh to all the Israelites that went there.
