1 Samuel 1:21-28 - Samuel Given To The Lord
21 And the man Elkanah with all his family went up to make the year's offering to the Lord, and to give effect to his oath. 22 But Hannah did not go, for she said to her husband, I will not go till the child has been taken from the breast, and then I will take him with me and put him before the Lord, where he may be for ever.
23 And her husband Elkanah said to her, Do whatever seems right to you, but not till you have taken him from the breast; only may the Lord do as he has said. So the woman, waiting there, gave her son milk till he was old enough to be taken from the breast. 24 Then when she had done so, she took him with her, with a three-year old ox and an ephah of meal and a skin full of wine, and took him to the house of the Lord at Shiloh: now the child was still very young. 25 And when they had made an offering of the ox, they took the child to Eli.
26 And she said, O my lord, as your soul is living, my lord, I am that woman who was making a prayer to the Lord here by your side: 27 My prayer was for this child; and the Lord has given him to me in answer to my request: 28 So I have given him to the Lord; for all his life he is the Lord's. Then he gave the Lord worship there.
