1 Samuel 1:10-12

10She, 1greatly distressed, prayed to the Lord and wept bitterly. 11And she 2made a vow and said, “Lord of armies, if You will indeed 3look on the affliction of Your bond-servant and remember me, and not forget Your bond-servant, but will give Your bond-servant a 4son, then I will give him to the Lord all the days of his life, and 5a razor shall never come on his head.”

12Now it came about, as she 6continued praying before the Lord, that Eli was watching her mouth.
