Romans 9:7-9

Douay-Rheims 1899 American Edition

⁷ Neither are all they that are the seed of Abraham, children; but in Isaac shall thy seed be called:

⁸ That is to say, not they that are the children of the flesh, are the children of God; but they, that are the children of the promise, are accounted for the seed.

⁹ For this is the word of promise: According to this time will I come; and Sara shall have a son.
