1 Samuel 2:13-15

13 And the ruling of the priests with the people was that when any man slaughtered a slaughtering, the priest’s servant shall come with a three-pronged flesh-hook in his hand while the meat was cooking,

14 and shall strike it into the basin, or kettle, or cauldron, or pot. And the priest would take for himself all that the flesh-hook brought up. Thus they did in Shiloh to all Yisra’ĕl who came there.

15 Also, before they burned the fat, the priest’s servant would come and say to the man who slaughtered, “Give meat for roasting to the priest, for he does not accept cooked meat from you, but raw.”
