These chapters are on Jesus’s discourse about the destruction of Jerusalem and the temple (AD 70) and then the Second Coming, which has not happened yet, 2000 years later (and counting). Looking at the chapters side by side clarifies what he really taught.
The widow’s generous gift is announced; Jesus predicts wars and persecutions and the destruction of Jerusalem and the temple. He teaches the lesson of the fig tree and all the trees and says the destruction shall happen in his generation. He then says that the Son of Man is coming back (later). He warns his disciples to watch and not get intoxicated.
Things are not so clear-cut as I had thought they were. Please be sure to check out my photos of the Arch of Titus at the end; they show rhe Romans stomped all over the Jerusalem temple.
