Romans 9:10-16

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.”

14What shall we say then? Is there unrighteousness with God? Certainly not!

15For He says to Moses, “I will have mercy on whomever I will have mercy, and I will have compassion on whomever I will have compassion.”

16So then it is not of him who wills, nor of him who runs, but of God who shows mercy.
