1 Samuel 1:22, 24-28

But Hannah went not up; for she said unto her husband, I will not go up until the child be weaned; and then I will bring him, that he may appear before Jehovah, and there abide for ever.

And when she had weaned him, she took him up with her, with three bullocks, and one ephah of meal, and a bottle of wine, and brought him unto the house of Jehovah in Shiloh: and the child was young. And they slew the bullock, and brought the child to Eli. And she said, Oh, my lord, as thy soul liveth, my lord, I am the woman that stood by thee here, praying unto Jehovah. For this child I prayed; and Jehovah hath given me my petition which I asked of him: therefore also I have granted him to Jehovah; as long as he liveth he is granted to Jehovah. And he worshipped Jehovah there.
