1 Samuel 1:20-23

It came about in due time, after Hannah had conceived, that she gave birth to a son; she named him Samuel, saying, “Because I have asked for him from the LORD.” Then the man Elkanah and all his household went up to offer to the LORD the yearly sacrifice and pay his vow. But Hannah did not go up, for she said to her husband, “I will not go up until the child is weaned; and then I will bring him, so that he may appear before the LORD and remain there as long as he lives.” Elkanah her husband said to her, “Do what seems best to you. Wait until you have weaned him; only may the LORD establish and confirm His word.” So the woman remained [behind] and nursed her son until she weaned him.
