For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.

For it is written, "Rejoice, you barren who don't bear. Break forth and shout, you that don't travail. For more are the children of the desolate than of her who has a husband."

However what does the Scripture say? "Throw out the handmaid and her son, for the son of the handmaid will not inherit with the son of the free woman."
