23 But the one by the female slave was born according to human descent, and the one by the free woman through the promise,
24 which things are spoken allegorically, for these women are two covenants, one from Mount Sinai, bearing children for slavery, who is Hagar.
25 Now Hagar is Mount Sinai in Arabia, and corresponds to the present Jerusalem, for she is a slave with her children.
26 But the Jerusalem above is free, which is our mother.
27 For it is written, “Rejoice, O barren woman, who does not give birth to children; burst out and shout, you who do not have birth pains, because many are the children of the desolate woman, even more than those of the one who has a husband.”
28 But you, brothers, are children of the promise, just as Isaac.
29 But just as at that time the child born according to human descent persecuted the child born according to the Spirit, so also now.
