Romans 9:7-9

ACV(i) 7 nor, because they are Abraham's seed, are they all children, rather, In Isaac a seed will be called for thee. 8 That is, the children of the flesh, these are not children of God, instead, the children of the promise are reckoned for seed. 9 For this is the word of promise: At this time I will come, and there will be a son by Sarah.
