Galatians 4:21-27

21Tell me, you who want to live under the law, do you know what the law actually says?

22The Scriptures say that Abraham had two sons, one from his slave wife and one from his freeborn wife.

23The son of the slave wife was born in a human attempt to bring about the fulfillment of God’s promise. But the son of the freeborn wife was born as God’s own fulfillment of his promise.

24These two women serve as an illustration of God’s two covenants. The first woman, Hagar, represents Mount Sinai where people received the law that enslaved them.

25And now Jerusalem is just like Mount Sinai in Arabia, because she and her children live in slavery to the law.

26But the other woman, Sarah, represents the heavenly Jerusalem. She is the free woman, and she is our mother.

27As Isaiah said, “Rejoice, O childless woman, you who have never given birth! Break into a joyful shout, you who have never been in labor! For the desolate woman now has more children than the woman who lives with her husband!”
