Romans 9:15

12 it was said to her, "The elder will serve the younger."

13 Even as it is written, "Jacob I loved, but Esau I hated."

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

15 For he said to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion."

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

17 For the scripture says to Pharaoh, "For this very purpose I caused you to be raised up, that I might show in you my power, and that my name might be published abroad in all the earth."

18 So then, he has mercy on whom he desires, and he hardens whom he desires.
