1 Samuel 1:10-13

And she {was} in bitterness of soul, and prayed unto the LORD, and wept sore. {in...: Heb. bitter of soul} And she vowed a vow, and said, O LORD of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the LORD all the days of his life, and there shall no razor come upon his head. {a man...: Heb. seed of men} And it came to pass, as she continued praying before the LORD, that Eli marked her mouth. {continued...: Heb. multiplied to pray} Now Hannah, she spake in her heart; only her lips moved, but her voice was not heard: therefore Eli thought she had been drunken.
