24These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. 25Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. 26But the Jerusalem that is above is free, and she is our mother.
27For it is written: “Be glad, barren woman, you who never bore a child; shout for joy and cry aloud, you who were never in labor; because more are the children of the desolate woman than of her who has a husband.” Isaiah 54:128Now you, brothers and sisters, like Isaac, are children of promise.
