Galatians 4:26-29

Murdock(i) 26 But the Jerusalem above, is the free woman, who is the mother of us. 27 For it is written, Be joyful, thou barren, who bearest not: exult and shout, thou who hast not travailed: for more numerous are the children of the desolate than the children of the married woman. 28 Now we, my brethren, like Isaac, are the children of the promise. 29 And as then, he that was born after the flesh, persecuted him who was born of the Spirit; so also is it now.
