Romans 9:7-13

7nor are they all children because they are the seed of Abraham; but, “In Isaac your seed shall be called.”

8That is, those who are the children of the flesh, these are not the children of God; but the children of the promise are counted as the seed.

9For this is the word of promise: “At this time I will come and Sarah shall have a son.”

10And not only this, but when Rebecca also had conceived by one man, even by our father Isaac

11(for the children not yet being born, nor having done any good or evil, that the purpose of God according to election might stand, not of works but of Him who calls),

12it was said to her, “The older shall serve the younger.”

13As it is written, “Jacob I have loved, but Esau I have hated.”
