22 For it is written that Abraham had two sons, aone by the bondwoman and bone by the free woman.

23 But athe son by the bondwoman 1was born according to the flesh, and bthe son by the free woman through the promise.

24 1aThis is allegorically speaking, for these women are two covenants: one proceeding from bMount Sinai bearing children 2who are to be cslaves; 3she is Hagar.

25 Now this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.

26 But athe Jerusalem above is free; 1she is our mother.

27 For it is written,

“aRejoice, barren woman who does not bear;

Break forth and shout, you who are not in labor;

For more numerous are the children of the desolate

Than of the one who has a husband.”

28 And you brethren, alike Isaac, are bchildren of promise.

29 But as at that time ahe who was born according to the flesh bpersecuted him who was born according to the Spirit, cso it is now also.

30 But what does the Scripture say?

“aCast out the bondwoman and her son,

For bthe son of the bondwoman shall not be an heir with the son of the free woman.”

31 So then, brethren, we are not children of a bondwoman, 1but of the free woman.
