The study deals with a much-debated text in Paul's Letter to the Romans, 9:30-10:21. The study in particular analyses Paul's use and interpretation of Deuteronomy 30:12-14 in Romans 10:4-17. Scholars have characterized Paul's exegesis here as idiosyncratic, fanciful, baffling, and arbitrary. By a comparison with Jewish writings, such as the writings of Philo of Alexandria and Baruch, the thesis is argued that Paul's treatment of Deuteronomy 30:12-14 can be located within Jewish exegetical method, expository structure, terminology as well as content and context. The author interprets Romans 9:30-10:21 afresh, and throws new light on Paul's exposition of Deuteronomy 30:12-14.
