Ancient authors relied far more on the works of their predecessors than one would ever guess from a study of their explicit quotations. The same holds true for modern scholars who have the benefit of computerized reference systems and automatic footnotes to ease their task.

The present work is a slightly revised version of a Ph.D. dissertation submitted to Duke University in the summer of 1990. Many of those who have contributed the most to this project would never find mention in the footnotes. Special thanks are due to Dr. Moody Smith, my adviser, who allowed me to pursue my interests well beyond the usual limits of a Duke dissertation. His own studies in early Christian exegesis made him an invaluable resource at numerous points along the way. Dr. Melvin Peters, in a class on the Septuagint, was the first to suggest that I explore Paul's use of the Greek biblical text. His faith in my abilities has been a constant source of encouragement. Dr. Orval Wintermute shared the fruit of years of careful research as we examined the biblical exegesis of the Qumran community and the Jewish “pseudepigrapha.” Discussions with friends and colleagues likewise helped to hone my thinking in a number of key areas.

Thanks are also due to Dr. Graham Stanton for accepting this volume for publication in the SNTS series, and to Alex Wright and his colleagues at Cambridge University Press for handling a difficult manuscript with skill and aplomb.
