Romans 9:10

7 nor because they are seed of Abraham [are] all children, but -- `in Isaac shall a seed be called to thee;`

8 that is, the children of the flesh -- these [are] not children of God; but the children of the promise are reckoned for seed;

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

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

11 (for they being not yet born, neither having done anything good or evil, that the purpose of God, according to choice, might remain; not of works, but of Him who is calling,) it was said to her --

12 `The greater shall serve the less;`

13 according as it hath been written, `Jacob I did love, and Esau I did hate.`
