1st Samuel 1:11 And she vowed a vow, and said, O Lord of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the Lord all the days of his life, and there shall no razor come upon his head.
[Patriarchs & Prophets pp 570>571] The high priest was deeply moved, for he was a man of God; and in place of rebuke he uttered a blessing: “Go in peace: and the God of Israel grant thee thy petition that thou hast asked of Him.” Hannah's prayer was granted; she received the gift for which she had so earnestly entreated. As she looked upon the child, she called him Samuel—“asked of God.” As soon as the little one was old enough to be separated from his mother, she fulfilled her vow.
She loved her child with all the devotion of a mother's heart; day by day, as she watched his expanding powers and listened to his childish prattle, her affections entwined about him more closely. He was her only son, the special gift of Heaven; but she had received him as a treasure consecrated to God, and she would not withhold from the Giver His own. Once more Hannah journeyed with her husband to Shiloh and presented to the priest, in the name of God, her precious gift, saying, “For this child I prayed; and the Lord hath given me my petition which I asked of Him: therefore also I have lent him to the Lord; as long as he liveth he shall be lent to the Lord.”
Eli was deeply impressed by the faith and devotion of this woman of Israel. Himself an overindulgent father, he was awed and humbled as he beheld this mother's great sacrifice in parting with her only child, that she might devote him to the service of God. He felt reproved for his own selfish love, and in humiliation and reverence he bowed before the Lord and worshiped.
1st Samuel 1:17 Then Eli answered and said, Go in peace: and the God of Israel grant thee thy petition that thou hast asked of him. 18 And she said, Let thine handmaid find grace in thy sight. So the woman went her way, and did eat, and her countenance was no more sad. 19 And they rose up in the morning early, and worshipped before the Lord, and returned, and came to their house to Ramah: and Elkanah knew Hannah his wife; and the Lord remembered her.
May The Lord add His blessing to the study of His word. God bless!
