Galatians

²⁶But Jerusalem which is above is free, which is the mother of us all. ²⁷For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband. ²⁸Now we, brethren, as Isaac was, are the children of promise. ²⁹But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now. ³⁰Nevertheless 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 freewoman. ³¹So then, brethren, we are not children of the bondwoman, but of the free.
