Mark 13:8
For nations will wage war against one another, and kingdoms will attack one another. And earthquakes will happen at various places [in the world], and there will be famines. These things are [only] the beginning of terrible times.
Luke 21:9-10
And when you hear of wars and uprisings [going on], do not be afraid, for such things must necessarily happen first. But the end will not come right away." [Note: By "the end" here Jesus probably alludes to the downfall of Jerusalem, in AD 70, with its attending destruction of the Temple buildings].
Luke 21:22-24
For these are times for punishment [i.e., to be inflicted on Jerusalem], so that everything written [i.e., by the prophets] may be fulfilled [i.e., about Jerusalem's destruction. See Dan. 9:26-27].
