For Hagar represents Mount Sinai in Arabia, and corresponds to the present Jerusalem, for she is in bondage with her children.

For it is written: Rejoice you barren, that do not bear: break forth and cry aloud, you that travail not: for many more are the children of the deserted, than of her that had the husband of the deserted.

But what says the scripture? Cast out the bondwoman and her son; for the son of the bondwoman shall not be heir with the son of the free-woman.
