1 Samuel 1:21-23

21 And the man Elkanah, and all his house, went up to offer unto the Lord the yearly sacrifice, and his vow. 22 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 the Lord, and there abide for ever. 23 And Elkanah her husband said unto her, Do what seemeth thee good; tarry until thou have weaned him; only the Lord establish his word. So the woman abode, and gave her son suck until she weaned him.
