Now Hagar is (represents) Mount Sinai in Arabia and she corresponds to the present Jerusalem, for she is in slavery with her children.

But the Jerusalem above [that is, the way of faith, represented by Sarah] is free; she is our mother.

For it is written [in the Scriptures],

“Rejoice, o barren woman who has not given birth;
Break forth into a [joyful] shout, you who are not in labor;
For the desolate woman has many more children
Than she who has a husband.”
