1 Samuel 1:25-28

Then they slaughtered the bull, and they brought the child to Eli. And 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. For this child I prayed, and the LORD has granted me my petition that I made to him. Therefore I have lent him to the LORD. As long as he lives, he is lent to the LORD.” And he worshiped the LORD there.
