The Gospel according to Luke contains two passages which allude, with some particularity, to a forthcoming siege and destruction of Jerusalem; viz. XIX, 42–4, XXI, 20–4.The latter of these two passages (with which we may conveniently begin) stands in a context where Luke, to all appearance, is using the Gospel according to Mark as a source. The Marcan parallel to Luke XXI, 20–24 forms part of what is often called the ‘Synoptic Apocalypse’, or, more appropriately, the ‘Apocalyptic Discourse’, since its literary form is not that of an apocalypse; it is in the main a Mahnrede making use of apocalyptic motives, and concluding with a few sentences of straightforward prediction in the apocalyptic manner (XIII, 24–7).
