18 But Samuel did the work of the Lord's house, while he was a child, dressed in a linen ephod. 19 And his mother made him a little robe and took it to him every year when she came with her husband for the year's offering. 20 And every year Eli gave Elkanah and his wife a blessing, saying, May the Lord give you offspring by this woman in exchange for the child you have given to the Lord. And they went back to their house. 21 And the Lord had mercy on Hannah and she gave birth to three sons and two daughters. And the young Samuel became older before the Lord. 22 Now Eli was very old; and he had news from time to time of what his sons were doing to all Israel. 23 And he said to them, Why are you doing such things? for from all this people I get accounts of your evil ways. 24 No, my sons, the account which is given me, which the Lord's people are sending about, is not good. 25 If one man does wrong to another, God will be his judge: but if a man's sin is against the Lord, who will take up his cause? But they gave no attention to the voice of their father, for it was the Lord's purpose to send destruction on them. 26 And the young Samuel, becoming older, had the approval of the Lord and of men.

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.
