1 Samuel 1:20-23

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.
