Revelation 20:3-5

Revised Standard Version

³ and threw him into the pit, and shut it and sealed it over him, that he should deceive the nations no more, till the thousand years were ended. After that he must be loosed for a little while.

⁴ Then I saw thrones, and seated on them were those to whom judgment was committed. Also I saw the souls of those who had been beheaded for their testimony to Jesus and for the word of God, and who had not worshiped the beast or its image and had not received its mark on their foreheads or their hands. They came to life, and reigned with Christ a thousand years. ⁵ The rest of the dead did not come to life until the thousand years were ended. This is the first resurrection.
