I Samuel 1:24-28

Now when she had weaned him, she took him up with her, with three bulls, one ephah of flour, and a skin of wine, and brought him to the house of the LORD in Shiloh. And the child was young. Then they slaughtered a bull, and brought the child to Eli. And she said, “O my lord! As your soul lives, my lord, I am the woman who stood by you here, praying to the LORD. For this child I prayed, and the LORD has granted me my petition which I asked of Him. Therefore I also have lent him to the LORD; as long as he lives he shall be lent to the LORD.” So they worshiped the LORD there.
