1 Samuel 1:20-23

It came about in due time, after Hannah had conceived, that she gave birth to a son; and she named him Samuel, saying, “Because I have asked him of the LORD.” Then the man Elkanah went up with all his household 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; then I will bring him, that he may appear before the LORD and stay there forever.” Elkanah her husband said to her, “Do what seems best to you. Remain until you have weaned him; only may the LORD confirm His word.” So the woman remained and nursed her son until she weaned him.
