1 Samuel 1:9-11

Once, after they had eaten their meal in Shiloh, Hannah got up. Now Eli the priest was sitting on a chair near the entrance to the LORD’s house. Hannah was so sad that she cried and prayed to the LORD. She made a promise, saying, “LORD All-Powerful, see how sad I am. Remember me and don’t forget me. If you will give me a son, I will give him back to you all his life, and no one will ever cut his hair with a razor.”
