1 Samuel 1:11; 1 Samuel 1:22

11 And she made a vow, saying, “LORD Almighty, if you will only look on your servant’s misery and remember me, and not forget your servant but give her a son, then I will give him to the LORD for all the days of his life, and no razor will ever be used on his head.”

22 Hannah did not go. She said to her husband, “After the boy is weaned, I will take him and present him before the LORD, and he will live there always.”
