I don't see how those verses can be interpreted as saying that unbelieving Jews profited from their circumcision. "Circumcision verily profiteth if thou keep the law: but if thou break the law, thy circumcision is made uncircumcision." Romans 2:25. "And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe. . ." Romans 4:11. "They are not all Israel, which are of Israel." Romans 9:6. "I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy." Romans 9:15, 16.
