1 Samuel 2:13-15

Amplified Bible

¹³ and the custom of the priests with [the sacrifices of] the people. When any man was offering a sacrifice, the priest’s servant would come while the meat was boiling, with a three-pronged [meat] fork in his hand; ¹⁴ then he would thrust it into the pan, or kettle, or caldron, or pot; everything that the fork brought up the priest would take for himself. This is what they did in Shiloh to all [the sacrifices of] the ^[a]Israelites who came there. ¹⁵ Also, before they burned (offered) the fat, the priest’s servant would come and say to the man who was sacrificing, “Give the priest meat to roast, since he will not accept boiled meat from you, only raw.”
