**21** Tell me, you who desire to be under the law, do you not hear the law? **22** For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. **23** But he who was of the bondwoman was born according to the flesh, and he of the freewoman through promise, **24** which things are symbolic. For these are the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar—**25** for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children—**26** but the Jerusalem above is free, which is the mother of us all. **27** For it is written: “Rejoice, O barren, You who do not bear! Break forth and shout, You who are not in labor! For the desolate has many more children Than she who has a husband.” **28** Now we, brethren, as Isaac was, are children of promise. **29** But, as he who was born according to the flesh then persecuted him who was born according to the Spirit, even so it is now. **30** Nevertheless what does the Scripture say? “Cast out the bondwoman and her son, for the son of the bondwoman shall not be heir with the son of the freewoman.” **31** So then, brethren, we are not children of the bondwoman but of the free.
