THIS MIGHT SURPRISE YOU
The answer
Nowhere else. The thousand years are named in Revelation 20, and no other book of the Bible has them. The "first resurrection" of Revelation 20:5 is found only here too.
Why it’s interesting
Satan's release "for a little while" after the thousand years (Revelation 20:3) is another idea only Revelation has.
