25for this Hagar is mount Sinai in Arabia, and doth correspond to the Jerusalem that now [is], and is in servitude with her children,
26and the Jerusalem above is the free-woman, which is mother of us all,
27for it hath been written, `Rejoice, O barren, who art not bearing; break forth and cry, thou who art not travailing, because many [are] the children of the desolate -- more than of her having the husband.`
28And we, brethren, as Isaac, are children of promise,
29but as then he who was born according to the flesh did persecute him according to the spirit, so also now;
30but what saith the Writing? `Cast forth the maid-servant and her son, for the son of the maid-servant may not be heir with the son of the free-woman;`
31then, brethren, we are not a maid-servant`s children, but the free-woman`s.
