V.1-3 Satan is cast into the bottomless pit — not the lake of fire yet — for one thousand years — during the millennium see chart.
V.4 The prophets Daniel and John see the same thrones; Daniel saw them occupied (Dan. 7:99I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire. (Daniel 7:9)), but redemption has taken place, so John sees people sitting on them. Those who were killed in the tribulation for witnessing for Jesus as well as we who are believers, will be living and reigning with Christ a thousand years over the earth, not on the earth.
V.5-6 Every other dead person will lie in his grave until the great white throne judgment at the end of the thousand years.
V 7-10 At the end of the millennium (thousand years), Satan is going to be brought out of the pit and let loose for a little while. Even after seeing the Lord Jesus reign in righteousness for those thousand years, millions (without number), will turn back to follow Satan. But punishment will fall on them.
V.10 Satan the deceiver. If we could only realize how clever a deceiver he is, we would not be fooled by him so often today. And remember he is a religious deceiver. Here is his awful end.
V.11-15 Now comes the final judgment. Only the lost stand here. Be very sure you understand this. There is no such thing as a general judgment day for everyone to stand before God to find out where they are to go, heaven or hell. Those who stand here are they who have rejected God from Cain down to the last person born.
