1 Samuel 2:12-17

The sons of Eli [Hophni and Phinehas] were worthless (dishonorable, unprincipled) men; they did not know [nor respect] the LORD 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; 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 Israelites who came there. 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.” If the man said to him, “Certainly they are to burn (offer) the fat first, and then you may take as much as you want,” then the priest’s servant would say, “No! You shall give it to me now or I will take it by force.” So the sin of the [two] young men [Hophni and Phinehas] was very great before the LORD, for the men treated the offering of the LORD disrespectfully.
