“After forty years had passed, an angel appeared to him in the wilderness of Mount Sinai, in the flame of a burning thorn bush.

This is the one who was in the congregation in the wilderness together with the angel who was speaking to him on Mount Sinai, and who was with our fathers; and he received living oracles to pass on to you.

This is allegorically speaking, for these women are two covenants: one proceeding from Mount Sinai bearing 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 in slavery with her children.
