Galatians 4:21-27

²¹Tell me, you who want to be under law, do you not listen to the Law? ²²For it is written that Abraham had two sons, one by the slave woman and one by the free woman. ²³But the son by the slave woman was born according to the flesh, and the son by the free woman through the promise. ²⁴This is speaking allegorically, for these women are two covenants: one coming from Mount Sinai giving birth to children who are to be slaves; she is Hagar. ²⁵Now this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is enslaved with her children. ²⁶But the Jerusalem above is free; she is our mother. ²⁷For it is written:

“Rejoice, infertile one, you who do not give birth;

Break forth and shout, you who are not in labor;

For the children of the desolate one are more numerous

Than those of the one who has a husband.”
