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.

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

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.
