Revelation 20:4-8

Then I saw thrones, and they sat on them, and judgment was given to them. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had not worshiped the beast or his image, and had not received the mark on their foreheads and on their hands; and they came to life and reigned with Christ for a thousand years.

The rest of the dead did not come to life until the thousand years were completed. This is the first resurrection.

Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ, and will reign with Him for a thousand years. Satan Freed and Doomed

When the thousand years are completed, Satan will be released from his prison,

and will come out to deceive the nations which are at the four corners of the earth, Gog and Magog, to gather them together for the war; the number of them is like the sand of the seashore.
