Romans 9:7 BBE

⁵  Whose are the fathers, and of whom came Christ in the flesh, who is over all, God, to whom be blessing for ever. So be it.

⁶  But it is not as if the word of God was without effect. For they are not all Israel, who are of Israel:

⁷  And they are not all children because they are the seed of Abraham; but, In Isaac will your seed be named.

⁸  That is, it is not the children of the flesh, but the children of God's undertaking, who are named as the seed.

⁹  For this is the word of God's undertaking, At this time will I come, and Sarah will have a son.
