Romans 9:9-13

Romans 9:9-13. For this is the word of promise. At this time will I come, and Sarah shall have a son. And not only this; but when Rebecca also had conceived by one, even by our father Isaac; (for the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;) It was said unto her, The elder shall serve the younger. As it is written, Jacob have I loved, but Esau have I hated.

So, then, there is no claim of birth, for he that had the claim of birth, even Esau, is passed by. There is, indeed, no claim at all, for God gives freely, according to his own will, blessing the sons of men.
