Romans 9:6-8 Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:

KJV⁽ⁱ⁾ ⁶ Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: 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.

RKJNT⁽ⁱ⁾ ⁶ But it is not as though the word of God has had no effect. For they are not all Israel, who are descended from Israel: 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.
