1. Revelation 20:4 (ESV)
  2. Exposition

Are these the souls of those given authority to judge?

Revelation 20:4 (ESV)

4 Then I saw thrones, and seated on them were those to whom the authority to judge was committed. Also I saw the souls of those who had been beheaded for the testimony of Jesus and for the word of God, and those 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 for a thousand years.

These souls might be the same as those who are given the authority to judge, but this is not clear from the text.
