21Tell me, ye that desire to be under the law, do ye not hear the law?
22For it is written, that Abraham had two sons, one by the handmaid, and one by the freewoman.
23Howbeit the [son] by the handmaid is born after the flesh; but the [son] by the freewoman [is born] through promise.
24Which things contain an allegory: for these [women] are two covenants; one from mount Sinai, bearing children unto bondage, which is Hagar.
25Now this Hagar is mount Sinai in Arabia and answereth to the Jerusalem that now is: for she is in bondage with her children.
26But the Jerusalem that is above is free, which is our mother.
27For it is written, Rejoice, thou barren that bearest not; Break forth and cry, thou that travailest not: For more are the children of the desolate than of her that hath the husband.
