Revelation 20:3-5

Living Bible

³ and threw him into the bottomless pit, which he then shut and locked so that he could not fool the nations anymore until the thousand years were finished. Afterwards he would be released again for a little while.

⁴ Then I saw thrones, and sitting on them were those who had been given the right to judge. And I saw the souls of those who had been beheaded for their testimony about Jesus, for proclaiming the Word of God, and who had not worshiped the Creature or his statue, nor accepted his mark on their foreheads or their hands. They had come to life again and now they reigned with Christ for a thousand years.

⁵ This is the First Resurrection. (The rest of the dead did not come back to life until the thousand years had ended.)
