MLV(i)
23 But indeed the one from the maidservant has been born according to the flesh, but the one from the free woman has been born through the promise.
24 Which things are allegorized; for these women are two covenants; indeed one from Mount Sinai, who is Hagar, giving-birth to children into bondage.
25 For this Hagar is Mount Sinai in Arabia and corresponds to the Jerusalem which is now and she is enslaved with her children.
