Romans 9:7-13 Nor are they all the children of Abraham because they are descended from him: but, Through Isaac shall your descendants be named.

RKJNT⁽ⁱ⁾ ⁷ Nor are they all the children of Abraham because they are descended from him: but, Through Isaac shall your descendants be named. ⁸ That is, It is not those who are the children of the flesh who are the children of God: but the children of the promise are counted as descendants. ⁹ For this is the word of the promise, At this time I will come, and Sarah shall have a son. ¹⁰ And not only this; but also when Rebekah had conceived children by one man, our father Isaac; ¹¹ (Though they were not yet born, and had done nothing good or evil, in order that the purpose of God according to his choice might stand, not because of works, but because of him who calls;) ¹² It was said to her, The elder shall serve the younger. ¹³ As it is written, Jacob I have loved, but Esau I have hated.
