Romans 9:6-13

6Not as though the word of God hath taken no effect. For they are not all Israel, who are descended from Israel: 7Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. 8That is, They who are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed. 9For this is the word of promise, At this time will I come, and Sarah shall have a son. 10And not only this ; but when Rebecca also had conceived by one, even by our father Isaac; 11(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;) 12It was said to her, The elder shall serve the younger.12 13As it is written, Jacob have I loved, but Esau have I hated.
