22 For it is written, that Abraham had two sons; the one by the bondwoman, the other by the freewoman.
23 But the one by the bondwoman was born after the flesh; while the one by the freewoman was through the promise.
24 Which things are written allegorically; for these women are two covenants; the one from Mount Sinai, who beareth children into bondage, which is Hagar;
25 for the word Hagar is Mount Sinai in Arabia; and she corresponds to the Jerusalem now existing, for she is in bondage with her children;
26 but the Jerusalem that is above is free, and she is our mother.
