22Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.
23Now the son by the servant-woman has his birth after the flesh; but the son by the free woman has his birth through the undertaking of God.
24Which things have a secret sense; because these women are the two agreements; one from the mountain of Sinai, giving birth to servants, which is Hagar.
25Now this Hagar is the mountain Sinai in Arabia, and is the image of the Jerusalem which now is: which is a servant with her children.
26But the Jerusalem on high is free, which is our mother.
27For it is in the Writings, You who have never given birth, be glad; give cries of joy, you who have had no birth-pains; for the children of her who has been given up by her husband are more than those of the woman who has a husband.
28Now we, brothers, as Isaac was, are the children of the undertaking of God.
