Galatians 4:27-30 Douay-Rheims 1899 American Edition (DRA)
27 For it is written: Rejoice, thou barren, that bearest not: break forth and cry, thou that travailest not: for many are the children of the desolate, more than of her that hath a husband.
28 Now we, brethren, as Isaac was, are the children of promise.
29 But as then he, that was born according to the flesh, persecuted him that was after the spirit; so also it is now.
30 But what saith the scripture? Cast out the bondwoman and her son; for the son of the bondwoman shall not be heir with the son of the free woman.
