11 Also she vowed a vowe, and sayd, O Lord of hostes, if thou wilt looke on the trouble of thine handmaide, and remember me, and not forget thine handmaide, but giue vnto thine handmaide a manchilde, then I will giue him vnto the Lord all the dayes of his life, and there shall no rasor come vpon his head.
