22. For it is written that Abraham had two sons, one by the slave woman and one by the free woman.
23. But one—the son by the slave woman—was born naturally; while the other—the son by the free woman—was through the promise.
24. Now these things are being treated allegorically, for these are two covenants. One is from Mount Sinai, giving birth to slavery—this is Hagar.
25. But this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery along with her children.
26. But the Jerusalem above is free—she is our mother.
27. For 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.”
28. Now you, brothers and sisters—like Isaac, you are children of promise.
29. But just as at that time the one born according to the flesh persecuted the one born according to the Ruach, so it is now.
