KJV⁽ⁱ⁾ 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 Sarah shall have a son.

RKJNT⁽ⁱ⁾ ⁷ Nor are they all the children of Abraham because they are descended from him: but, Through Isaac shall your descendants be named. ⁸ That is, It is not those who are the children of the flesh who are the children of God: but the children of the promise are counted as descendants. ⁹ For this is the word of the promise, At this time I will come, and Sarah shall have a son.
