1 Samuel 1:24-28

And when she had weaned him, she took him up with her, with three bullocks, and one ephah of flour, and a bottle of wine, and brought him unto the house of the LORD in Shiloh: and the child was young.

And they slew a 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 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.
