21 (2:8) Tell me, you that wish to be under the law, do you not hear the law?
22 For it is written, that Abraham had two sons, one by a servant woman, and the other by a free woman.
23 But he by the servant woman was born of the flesh, and he by the free woman, by the promise.
24 These things are allegorical, for those [women] are two covenants, one from Mount Sinai, bearing children for servitude, which is Hagar;
25 for Hagar is Mount Sinai in Arabia; and the present Jerusalem answers to her, for she is in servitude with her children.
26 But the Jerusalem above is free, which is the mother of us;
27 for it is written, Rejoice, barren woman, that did not bear, break forth and cry, woman that had no pain, for the children of the desolate are more numerous than those of her who had a husband.
28 But we, brothers, like Isaac, are children of the promise.
29 But as then he that was born of the flesh persecuted him that was born of the Spirit, so also now.
30 But what says the Scripture? Cast out the servant-woman and her son; for the son of the servant woman shall not be an heir, with the son of the free.
31 Wherefore, brothers, we are not children of the servant woman, but of the free.
