Romans 9:10-16

10Not only that, but when Rebekah had conceived children by one man, our ancestor Isaac –

11even before they were born or had done anything good or bad (so that God’s purpose in election would stand, not by works but by his calling) –

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

13just as it is written: “Jacob I loved, but Esau I hated.”

14What shall we say then? Is there injustice with God? Absolutely not!

15For he says to Moses: “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”

16So then, it does not depend on human desire or exertion, but on God who shows mercy.
