No, it is not guesswork, my understanding comes from an OT prophecy which mirrors the Armageddon judgement mention in Rev 16:12-16.
I have referenced it many times on this forum, but people want to just ignore it. The verses are Isaiah 24:21-22. It talks of the judgement of the heavenly hosts as well as the judgement of the kings of the earth and that they will be gathered together and imprisoned in a pit for many days to await the time of their punishment.
This means that Satan, the beasts and the Little Horn, called the False prophet in the NT, and the kings of the earth who have helped to trample God's sanctuary and his earthly hosts, Israel, will all go into the pit, i.e. the Bottomless pit, immediately after God has judged them.
I would also reference and Daniel 7:2 and 9-12 that the four winds of heaven, i.e. spiritual entities that can only be wicked fallen heavenly hosts are the beasts described in Daniel 7.
On this forum there are many funny explanations given by some members as to how this is not so based on their reading of the NT prophecies.
Now you have demanded that must not dance around so much to avoid a simple question, yet you have made a claim that I am wrong but will not provide the scriptural evidence to show me where my understanding is wrong. You are the one who needs to stand up and put your reasoning forward to be judged.
