12 Now the sons of Eli were scoundrels who had no respect for the Lord 13 or for their duties as priests. Whenever anyone offered a sacrifice, Eli's sons would send over a servant with a three-pronged fork. While the meat of the sacrificed animal was still boiling, 14 the servant would stick the fork into the pot and demand that whatever it brought up be given to Eli's sons. All the Israelites who came to worship at Shiloh were treated this way. 15 Sometimes the servant would come even before the animal's fat had been burned on the altar. He would demand raw meat before it had been boiled so that it could be used for roasting. 16 The man offering the sacrifice might reply, "Take as much as you want, but the fat must be burned first." Then the servant would demand, "No, give it to me now, or I'll take it by force." 17 So the sin of these young men was very serious in the Lord 's sight, for they treated the Lord 's offerings with contempt.
Matthew Henry's Commentary on 1 Samuel 2:12-17
Commentary on 1 Samuel 2:11-26
(Read 1 Samuel 2:11-26)
Samuel, being devoted to the Lord in a special manner, was from a child employed about the sanctuary in the services he was capable of. As he did this with a pious disposition of mind, it was called ministering unto the Lord. He received a blessing from the Lord. Those young people who serve God as well as they can, he will enable to improve, that they may serve him better. Eli shunned trouble and exertion. This led him to indulge his children, without using parental authority to restrain and correct them when young. He winked at the abuses in the service of the sanctuary till they became customs, and led to abominations; and his sons, who should have taught those that engaged in the service of the sanctuary what was good, solicited them to wickedness. Their offence was committed even in offering the sacrifices for sins, which typified the atonement of the Saviour! Sins against the remedy, the atonement itself, are most dangerous, they tread under foot the blood of the covenant. Eli's reproof was far too mild and gentle. In general, none are more abandoned than the degenerate children of godly persons, when they break through restraints.
