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.
29But as in those days he who had birth after the flesh was cruel to him who had birth after the Spirit, even so it is now.
30What then do the Writings say? Send away the servant-woman and her son; for the son of the servant-woman will not have a part in the heritage with the son of the free woman.
31So, brothers, we are not children of the servant-woman, but of the free woman.
