"But when you see Jerusalem surrounded by armies, then know that its desolation is near." (Luke 21:20; NKJV)
Jesus speaks of the destruction of Jerusalem in Luke 21. The destruction of which he speaks took place in 70 AD. David Padfield has written some good material on this subject that I encourage you to read.
