1 Samuel 1:9-11

9 When the sacrifice had been offered, and they had eaten the meal, Hannah got up and went to pray. Eli was sitting in his chair near the door to the place of worship.

10 Hannah was brokenhearted and was crying as she prayed,

11 “LORD All-Powerful, I am your servant, but I am so miserable! Please let me have a son. I will give him to you for as long as he lives, and his hair will never be cut.” [6]
