1 Samuel 2:18-20

But Samuel was ministering before the LORD—a boy wearing a linen ephod. Each year his mother made him a little robe and took it to him when she went up with her husband to offer the annual sacrifice. Eli would bless Elkanah and his wife, saying, “May the LORD give you children by this woman to take the place of the one she prayed for and gave to the LORD.” Then they would go home.
