I'll look at that, it may be a different beast. But I know what beasts of Revelation are.
The beast in Daniel 7:19ff is, by the description, the four beasts of Daniel 7:1-12 acting in unison as just one beast.
At the present time there are four wicked heavenly host beasts plus the Little Horn who is also a wicked fallen heavenly host as well.
These five beasts will be judged in around 20 years' time at the beginning of the Seventh Age and they with the judged kings of the earth will be gathered together and imprisoned for many days, namely 1,000 years, to await the time of their punishment.
After the Bottomless Pit is unlocked, after the 1,000 years of their imprisonment, they will roam the face of the earth for around 24 years and at the end of this time period, the beast, the false prophet and Satan will be captured and dispatched into the Lake of Fire.
After Satan is dispatched into the lake of Fire, I believe that Jesus will be seen returning on the clouds to begin judging the righteousness of all of humanity from Adam who have and will be born right up and until the end of the seventh age.
Those who are judged to be unrighteous, will be dispatched into the lake of fire, while those who are judged to be righteous will receive their inheritance of the whole earth and gain everlasting life.
During the 1,000 years that the judged heavenly hosts are in the Bottomless Pit there will be a great harvest of Soul into the Kingdom of God.
The workers for the great harvest will be drawn from both the Israelites and Christ's disciples working together to show God's Glory to all.
This is how I understand the Seventh age will unfold.
Shalom
