DouayRheims(i)
26 But that Jerusalem which is above is free: which is our mother.
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.
31 So then, brethren, we are not the children of the bondwoman but of the free: by the freedom wherewith Christ has made us free.
