" His task is to proclaim the fulfilment of what God had revealed to the prophets of the past. The whole book is saturated with allusions to Old Testament prophecy, though there are no formal quotations. As a prophet himself, John need not quote his predecessors, but he takes up and reinterprets their prophecies, much as the later writers in the Old Testament prophetic tradition themselves took up and reinterpreted earlier prophecies. "

― Richard Bauckham , Theology of the Book of Revelation
