Romans 9:7-9

NHEB(i) 7 Neither, because they are Abraham's descendants, are they all children. But, "In Isaac will your descendants be called." 8 That is, it is not the children of the flesh who are children of God, but the children of the promise are counted as descendants. 9 For this is what the promise said, "At the appointed time I will come, and Sarah will have a son."
