21 Tell me, you who desire to be under the law, do you not listen to the law? 22 For it is written that Abraham had two sons, eone by a slave woman and fone by a free woman. 23 But gthe son of the slave was born according to the flesh, while hthe son of the free woman was born through promise. 24 Now this may be interpreted allegorically: these women are two icovenants. jOne is from Mount Sinai, bearing children for slavery; she is Hagar. 25 Now Hagar is Mount Sinai in Arabia;5 she corresponds to the present Jerusalem, for she is in slavery with her children. 26 But kthe Jerusalem above is free, and she is our mother. 27 For it is written,
l“Rejoice, O barren one who does not bear;
break forth and cry aloud, you who are not in labor!
For the children of the desolate one will be more
than those of the one who has a husband.”
