Galatians 4:22-28

22For it is written that Abraham had two sons, one by the slave woman and one by the free woman.

23But one—the son by the slave woman—was born naturally; while the other—the son by the free woman—was through the promise.

24Now these things are being treated allegorically, for these are two covenants. One is from Mount Sinai, giving birth to slavery—this is Hagar.

25But this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery along with her children.

26But the Jerusalem above is free—she is our mother.

27For it is written: “Rejoice, O barren woman who bears no children. Break forth and shout, you who suffer no labor pains. For more are the children of the desolate than of the one who has a husband.”

28Now you, brothers and sisters—like Isaac, you are children of promise.
