Galatians 4
23 Ref Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.
24 Ref Which things have a secret sense; because these women are the two agreements; one from the mountain of Sinai, giving birth to servants, which is Hagar.
25 Ref Now this Hagar is the mountain Sinai in Arabia, and is the image of the Jerusalem which now is: which is a servant with her children.
