8 In other words, those who are the sons of God are not those who are sons of the flesh, but those who are sons of the Promise; these are considered to be the offspring.
9 For the word of promise is this: "I will return at the proper time. And there shall be a son for Sarah."
10 And she was not alone. For Rebecca also, having conceived by Isaac our father, from one act,
11 when the children had not yet been born, and had not yet done anything good or bad (such that the purpose of God might be based on their choice),
12 and not because of deeds, but because of a calling, it was said to her: "The elder shall serve the younger."
13 So also it was written: "I have loved Jacob, but I have hated Esau."
14 What should we say next? Is there unfairness with God? Let it not be so!
