1 Samuel 2:13 (KJV)

And Elkanah went to Ramah to his house. And the child did minister unto the Lord before Eli the priest.

Now the sons of Eli were sons of Belial; they knew not the Lord.

And the priests’ custom with the people was, that, when any man offered sacrifice, the priest’s servant came, while the flesh was in seething, with a fleshhook of three teeth in his hand;

And he struck it into the pan, or kettle, or caldron, or pot; all that the fleshhook brought up the priest took for himself. So they did in Shiloh unto all the Israelites that came thither.

Also before they burnt the fat, the priest’s servant came, and said to the man that sacrificed, Give flesh to roast for the priest; for he will not have sodden flesh of thee, but raw.
