1 Samuel 2:18-20

18But Samuel ministered before the Lord, even as a child, wearing a linen ephod.

19Moreover 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.

20And 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.
