1 Samuel 1:10-12 Common English Bible (CEB)
10 Hannah was very upset and couldn’t stop crying as she prayed to the Lord. 11 Then she made this promise: “Lord of heavenly forces, just look at your servant’s pain and remember me! Don’t forget your servant! Give her a boy! Then I’ll give him to the Lord for his entire life. No razor will ever touch his head.”
12 As she kept praying before the Lord, Eli watched her mouth.
