Well I don't really care what people have to say about an upcoming tribulation that are writing about it only a couple of generations after it actually happened.

The seven-headed 10 horned beast was clearly indicative of the Roman empire. Rome had seven hills with 10 governors. In 70 AD Rome's armies surrounded Jerusalem and started to lay siege to it. The Christians who were familiar with their scriptures saying "when you see the abomination of desolation surrounding the holist of holies fleet of the mountains" we're completely ready when Rome's army inexplicably stop their siege and left. While the rest of Jerusalem was celebrating these Christians packed up and headed towards the mountains. Rome's army just came back a few days later and continued the siege eventually killing everyone.

During the siege there were all sorts of crazy things going on from secular accounts like histories of Josephus. There was a comet hanging in the sky over the city like a sword. There were eclipses, earthquakes, swarms of bugs, and of course cannibalism inside the city as food ran out. The streets were literally running with blood.

Remember before it's crucifixion Jesus said this generation shall not pass to all these things take place.

That generation passed.

Darbyism is absolutely unbiblical and bonkers.
