1 Samuel 1:20-28

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. Now when she had weaned him, she took him up with her, along with a three-year-old bull, an ephah of flour, and a leather bottle of wine [to pour over the burnt offering for a sweet fragrance], and she brought Samuel to the LORD’S house in Shiloh, although the child was young. Then they slaughtered the bull, and brought the child to Eli. Hannah said, “Oh, my lord! As [surely as] your soul lives, my lord, I am the woman who stood beside you here, praying to the LORD. For this child I prayed, and the LORD has granted me my request which I asked of Him. Therefore I have also dedicated him to the LORD; as long as he lives he is dedicated to the LORD.” And they worshiped the LORD there.
