Romans 9:8-10

Revised Geneva Translation

⁸ That is, those who are the children of the flesh are not the children of God. But the children of the promise are counted as the seed.

⁹ For this is a word of promise: “At this time I will come, and Sarah shall have a son”;

¹⁰ and not only her, but Rebecca also, when she had conceived by one, even by our Father, Isaac.
