1Sam 1:26-28

26And she said, “Oh, my lord! As you live, my lord, I am the woman who was standing here in your presence, praying to the Lord.27For this child I prayed; and the Lord has granted me the petition that I made to him.28Therefore I have lent him to the Lord; as long as he lives, he is given to the Lord.” She left him there for the Lord.
