^{21 Ref} Say, you whose desire it is to be under the law, do you not give ear to the law?

^{22 Ref} Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.

^{23 Ref} Now 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.

^{24 Ref} Which 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.

^{25 Ref} Now 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.

^{26 Ref} But the Jerusalem on high is free, which is our mother.

^{27 Ref} For 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.

^{28 Ref} Now we, brothers, as Isaac was, are the children of the undertaking of God.

^{29 Ref} But 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.

^{30 Ref} What 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.

^{31 Ref} So, brothers, we are not children of the servant-woman, but of the free woman.
