Galatians 4:26-31 WBT

26 But Jerusalem which is above is free, which is the mother of us all.
27 For 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 who 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 born] according to the Spirit, even so [it is] now.
30 Nevertheless, what saith the scripture? Cast out the bond-woman and her son: for the son of the bond-woman shall not be heir with the son of the free-woman.
31 So then, brethren, we are not children of the bond-woman, but of the free.
