BLB(i)
6 And it is not as that the word of God has failed. For not all who are of Israel, are these Israel.
7 Nor because they are seed of Abraham are all children. Rather, “In Isaac your offspring will be named.”
8 That is, the children of the flesh, these are not children of God; but the children of the promise are regarded as offspring.
9 For this is the word of the promise: “At this time I will come, and to Sarah there will be a son.”
10 And not only so, but also Rebecca, having conception by one, Isaac our father,
11 for they not yet having been born nor having done anything good or evil, so that the purpose of God according to election might stand,
12 not of works, but of the One calling, it was said to her, “The older will serve the younger.”
13 As it has been written: “Jacob I loved, but Esau I hated.”
