1 Samuel 1:25-28

When the bull had been sacrificed, they brought the boy to Eli, and she said to him, ‘Pardon me, my lord. As surely as you live, I am the woman who stood here beside you praying to the LORD. I prayed for this child, and the LORD has granted me what I asked of him. So now I give him to the LORD. For his whole life he shall be given over to the LORD.’ And he worshipped the LORD there.
