1 Samuel 2:12-14

12 And the sons of Ěli were sons of Beliya‛al — they did not know יהוה.

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.
