1 Samuel 1:25-28

Then they slaughtered the bull, and brought the boy to Eli. She said, “Oh, my lord! As your soul lives, my lord, I am the woman who stood here beside you, praying to the LORD. For this boy I prayed, and the LORD has given me my petition which I asked of Him. So I have also dedicated him to the LORD; as long as he lives he is dedicated to the LORD.” And he worshiped the LORD there.
