Romans

⁶But it is not as though the word of God hath come to nought. For they are not all Israel, which are of Israel: ⁷neither, because they are Abraham's seed, are they all children: but, In Isaac shall thy seed be called. ⁸That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed. ⁹For this is a word of promise, According to this season will I come, and Sarah shall have a son. ¹⁰And not only so; but Rebecca also having conceived by one, even by our father Isaac-- ¹¹for the children being not yet born, neither having done anything good or bad, that the purpose of God according to election might stand, not of works, but of him that calleth, ¹²it was said unto her, The elder shall serve the younger.
