Galatians 4:24-28

This is speaking allegorically, for these women are two covenants: one coming from Mount Sinai giving birth to children who are to be slaves; she is Hagar.

Now this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is enslaved with her children.

But the Jerusalem above is free; she is our mother.

For it is written: “Rejoice, infertile one, you who do not give birth; Break forth and shout, you who are not in labor; For the children of the desolate one are more numerous Than those of the one who has a husband.”

And you, brothers and sisters, like Isaac, are children of promise.
