For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children. But the Jerusalem that is above is free, which is the mother of us all. For it is written, “Rejoice, you barren who don’t bear. Break out and shout, you who don’t travail. For the desolate women have more children than her who has a husband.”
“Sing, barren, you who didn’t give birth! Break out into singing, and cry aloud, you who didn’t travail with child! For more are the children of the desolate than the children of the married wife,” says the LORD. “Enlarge the place of your tent, and let them stretch out the curtains of your habitations; don’t spare; lengthen your cords, and strengthen your stakes. For you will spread out on the right hand and on the left; and your offspring will possess the nations and settle in desolate cities. “Don’t be afraid, for you will not be ashamed. Don’t be confounded, for you will not be disappointed. For you will forget the shame of your youth. You will remember the reproach of your widowhood no more. For your Maker is your husband; the LORD of Armies is his name. The Holy One of Israel is your Redeemer. He will be called the God of the whole earth. For the LORD has called you as a wife forsaken and grieved in spirit, even a wife of youth, when she is cast off,” says your God.
