1 Samuel 2:13-14

13Now, this was how the priests dealt with the people who were offering sacrifices: While the meat was boiling, the priest’s servant would come with a three-pronged fork in his hand.

14Then he would stick it into the pot, kettle, cauldron, or pan. Whatever the fork brought up ⌞from the pot⌟ belonged to the priest. This is what the priests did in Shiloh to all the people of Israel who came there ⌞to sacrifice⌟.
