“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.”
King James Version (KJV)
1:11 Give him - That is, consecrate him to God's service in his temple. No razor - That is, he shall be a perpetual Nazarite.
