Romans 9:7-9

American Standard Version

⁷ neither, because they are Abraham’s seed, are they all children: but, ^[a]In Isaac shall thy seed be called. ⁸ That is, it is not the children of the flesh that are children of God; but the children of the promise are reckoned for a seed. ⁹ For this is a word of promise, ^[b]According to this season will I come, and Sarah shall have a son.
