Revelation 20:3-5

New International Reader's Version

³ Then he threw him into the Abyss. He locked it and sealed him in. This was to keep Satan from causing the nations to believe his lies anymore. Satan will be locked away until the 1,000 years are ended. After that, he must be set free for a short time.

⁴ I saw thrones. Those who had been given authority to judge were sitting on them. I also saw the souls of those whose heads had been cut off. They had been killed because they had spoken what was true about Jesus. They had also been killed because of the word of God. They had not worshiped the beast or its statue. They had not received its mark on their foreheads or hands. They came to life and ruled with Christ for 1,000 years. ⁵ This is the first resurrection. The rest of the dead did not come to life until the 1,000 years were ended.
