1 Samuel 2:14-16

14 and he struck it into the pan, or kettle, or caldron, or pot. All that the flesh-hook brought up the priest took with it. So they did in Shiloh to all the Israelites who came there.

15 And before they burned the fat, the priest's servant came, and said to the man who sacrificed, Give flesh to roast for the priest, for he will not have boiled flesh from thee, but raw.

16 And if the man said to him, They will surely burn the fat first, and then take as much as thy soul desires, then he would say, No, but thou shall give it to me now, and if not, I will take it by force.
