CAB⁽ⁱ⁾ ⁶ But it is not as though the word of God has failed. For not all those of Israel are of Israel, ⁷ nor are they all children because they are the seed of Abraham; but, "In Isaac your seed shall be called." ⁸ That is, those who are the children of the flesh, 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 I will come and Sarah shall have a son."
