In the same way we also, when we were children, were enslaved to the elementary principles of the world.

my little children, for whom I am again in the anguish of childbirth until Christ is formed in you!

Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar.

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

For it is written, “Rejoice, O barren one who does not bear; break forth and cry aloud, you who are not in labor! For the children of the desolate one will be more than those of the one who has a husband.”

Now you, brothers, like Isaac, are children of promise.

So, brothers, we are not children of the slave but of the free woman.
