Romans 9:7-9

New King James Version

^7 (A)nor are they all children because they are the seed of Abraham; but, ^(B)“In Isaac your seed shall be called.” ⁸ That is, those who are the children of the flesh, these are not the children of God; but ^(C)the children of the promise are counted as the seed. ⁹ For this is the word of promise: ^(D)“At this time I will come and Sarah shall have a son.”
