Pelagius — on Rom 9:6 (PELAGIUS'S COMMENTARY ON ROMANS)

“Since Paul has said above that he is upset that the people of Israel had been shut out of the kingdom by their own fault, for all these things had belonged to them, he shows here that those who do not believe are not sons of Abraham, lest someone think that he was opposed to all Jews and retort: "Did God then lie to Abraham?"”
