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.
