Romans 9:7-9

Authorized (King James) Version

⁷ neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. ⁸ That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed. ⁹ For this is the word of promise, At this time will I come, and Sara shall have a son.
