18 But Samuel ministered before the Lord, even as a child, wearing a linen ephod. 19 Moreover his mother used to make him a little robe, and bring it to him year by year when she came up with her husband to offer the yearly sacrifice. 20 And Eli would bless Elkanah and his wife, and say, "The Lord give you descendants from this woman for the loan that was given to the Lord." Then they would go to their own home. 21 And the Lord visited Hannah, so that she conceived and bore three sons and two daughters. Meanwhile the child Samuel grew before the Lord. 22 Now Eli was very old; and he heard everything his sons did to all Israel, and how they lay with the women who assembled at the door of the tabernacle of meeting. 23 So he said to them, "Why do you do such things? For I hear of your evil dealings from all the people. 24 No, my sons! For it is not a good report that I hear. You make the Lord's people transgress. 25 If one man sins against another, God will judge him. But if a man sins against the Lord, who will intercede for him?" Nevertheless they did not heed the voice of their father, because the Lord desired to kill them. 26 And the child Samuel grew in stature, and in favor both with the Lord and 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.
