1 Samuel 1:20-28

and it came to pass, when the time was come about, that Hannah conceived, and bare a son; and she called his name Samuel, saying, Because I have asked him of Jehovah. And the man Elkanah, and all his house, went up to offer unto Jehovah the yearly sacrifice, and his vow. 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 Elkanah her husband said unto her, Do what seemeth thee good; tarry until thou have weaned him; only Jehovah establish his word. So the woman tarried and gave her son suck, until she weaned him. 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.
