Romans 9:7-13

7nor because they are seed of Abraham [are] all children: but, In Isaac shall a seed be called to thee.

8That is, [they that are] the children of the flesh, these [are] not the children of 1God; but the children of the promise are reckoned as seed.

9For this word [is] of promise, According to this time I will come, and there shall be a son to Sarah.

10And not only [that], but Rebecca having conceived by one, Isaac our father,

11[the children] indeed being not yet born, or having done anything good or worthless (that the purpose of 2God according to election might abide, not of works, but of him that calls),

12it was said to her, The greater shall serve the less:

13according as it is written, I have loved Jacob, and I have hated Esau.
