1 Samuel 1:17-18, 26-28

Then Eli answered and said, Go in peace: and the God of Israel grant thee thy petition that thou hast asked of him. And she said, Let thine handmaid find grace in thy sight. So the woman went her way, and did eat, and her countenance was no more sad.

And she said, Oh my lord, as thy soul liveth, my lord, I am the woman that stood by thee here, praying unto the LORD. For this child I prayed; and the LORD hath given me my petition which I asked of him: therefore also I have lent him to the LORD; as long as he liveth he shall be lent to the LORD. And he worshipped the LORD there.
