On several occasions within the Pauline corpus, scriptural texts which seem to refer in their original contexts to the return of exiled or scattered Jews are appropriated as references to Gentile believers in Christ. This book is an investigation of four such instances (the use of Isa. 54:1 in Gal. 4:27, the catena of scriptural texts in 2 Cor. 6:16-18, Hos. 1:10 and 2:23 in Rom. 9:25-26 and Isa. 57:19 in Eph. 2:17). It offers insights into the exegesis of these particular verses and sheds light on several larger questions of Pauline hermeneutics and theology.
