Regardless of your view concerning the book of Revelation, you have to admit this is interesting.
John’s Revelation – “And there were noises and thundering and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth.” (16:18)
Josephus - “for there broke out a prodigious storm in the night, with the utmost violence, and very strong winds, with the largest showers of rain, with continued lightnings, terrible thunderings, and amazing concussions and bellowings of the earth, that was in an earthquake. These things were a manifest indication that some destruction was coming upon men, when the system of the world was put into this disorder; and any one would guess that these wonders foreshowed some grand calamities that were coming” (“Wars of the Jews” 4:4:5)
John’s Revelation – “Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath.” (16:19)
Josephus – “it so happened that the sedition at Jerusalem was revived, and parted into three factions, and that one faction fought against the other; which partition in such evil cases may be said to be a good thing, and the effect of divine justice.” (5:1:1)
John’s Revelation – “And great hail from heaven fell upon men, each hailstone about the weight of a talent.” (16:21)
Josephus - “Now the stones that were cast were of the weight of a talent, and were carried two furlongs and further. The blow they gave was no way to be sustained, not only by those that stood first in the way, but by those that were beyond them for a great space. As for the Jews, they at first watched the coming of the stone, for it was of a white color, and could therefore not only be perceived by the great noise it made, but could be seen also before it came by its brightness;” (5:6:3)
