Galatians 4:26

24These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar.

25For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.

26But the Jerusalem that is above is free, which is the mother of us all.

27For it is written, “Rejoice, you barren who don’t bear. Break out and shout, you who don’t travail. For the desolate women have more children than her who has a husband.”

28Now we, brothers, as Isaac was, are children of promise.
