In her deep anguish Hannah prayed to the LORD, weeping bitterly. 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 — 1 Samuel 1:10-11 (NIV)
