11 Then Elkanah went to Ramah to his house. And the child became the servant of the Lord under the direction of Eli the priest.
12 Now the sons of Eli were evil and good-for-nothing men, having no knowledge of the Lord. 13 And the priests' way with the people was this: when any man made an offering, the priest's servant came while the flesh was being cooked, having in his hand a meat-hook with three teeth; 14 This he put into the pot, and everything which came up on the hook the priest took for himself. This they did in Shiloh to all the Israelites who came there. 15 And more than this, before the fat was burned, the priest's servant would come and say to the man who was making the offering, Give me some of the flesh to be cooked for the priest; he has no taste for meat cooked in water, but would have you give it uncooked. 16 And if the man said to him, First let the fat be burned, then take as much as you will; then the servant would say, No, you are to give it to me now, or I will take it by force. 17 And the sin of these young men was very great before the Lord; for they gave no honour to the Lord's offerings.

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.
