It is generally agreed within Hebrew Bible scholarship that Zechariah 9-14 is filled with allusions to other books within the Hebrew canon. Rex Mason's doctoral dissertation in the early 1970s contributed significantly to the foundation of this consensus. However, although Mason's thesis remains a seminal work for those studying Deutero-Zechariah, it has never been published. This volume contains a publication of that work together with reflections from leading biblical scholars who have published on Zechariah 9-14. The volume is rounded off with a response by Mason to these scholars and a reflection on his own contribution. In some ways this project is a replication of the social process that gave rise to Zechariah 9-14, as the multiple authors bring out of this treasure that which is new and that which is old.
