21 Let me ask those of you who want to be subject to the Law: do you not hear what the Law says?
22 It says that Abraham had two sons, one by a slave woman, the other by a free woman.
23 His son by the slave woman was born in the usual way, but his son by the free woman was born as a result of God's promise.
24 These things can be understood as a figure: the two women represent two covenants. The one whose children are born in slavery is Hagar, and she represents the covenant made at Mount Sinai.
25 Hagar, who stands for Mount Sinai in Arabia, is a figure of the present city of Jerusalem, in slavery with all its people.
26 But the heavenly Jerusalem is free, and she is our mother.
27 For the scripture says:“Be happy, you childless woman!Shout and cry with joy, you who never felt the pains of childbirth!For the woman who was deserted will have more childrenthan the woman whose husband never left her.”
