What can one say about eschatology in the Old Testament? For a number of scholars there is no eschatology in the Old Testament and for many others eschatology only occurs at the fringes of that section of the Bible. Biblical Studies have tried to clarify the issues around eschatology, but different views remain. It is from this general background that this book examines the eschatology of the unit of Isa 65 and 66. The author throws new light on what Old Testament eschatology really is and offers a practical view of the unit of Isa 65 and 66, situating it within the larger Isaian tradition.
