9. For God's promise was made in these words: “At the right time I will come back, and Sarah will have a son.”
10. And this is not all. For Rebecca's two sons had the same father, our ancestor Isaac.
13. As the scripture says, “I loved Jacob, but I hated Esau.”
14. Shall we say, then, that God is unjust? Not at all.
15. For he said to Moses, “I will have mercy on anyone I wish; I will take pity on anyone I wish.”
16. So then, everything depends, not on what human beings want or do, but only on God's mercy.
