Revelation 20:13
Revelation 20:1313The sea gave up its dead, and Death and Hades gave up their dead, and each one was judged according to his deeds.
Watchtower commentary takes as the resurrection of all the dead — those in the sea, in the graves, and in Hades — for the post-millennial judgment. "The Grave" rendering of Hadēs preserves the Watchtower's soul-sleep doctrine: the dead were unconscious in the grave awaiting this resurrection moment. Then they are individually judged for their deeds during life and during the thousand years.
The verse is the universal resurrection scene. Whether the dead were in the sea, in graves, or in the unseen realm (Hades), all rise for judgment. The Reformed reading does not require soul-sleep: the OT and NT alike speak of conscious continuity after death (, , , ). The "judged individually according to their deeds" is the public evidential phase — the Lamb's book of life (v15) is the basis of survival. As says, a believer's work is tested by fire; some work is rewarded and some burned up, but the person "himself will be saved, even though only as through fire." Salvation is settled; the deeds are evaluated for reward, not for ground of inclusion.
The NWT renders Greek Hadēs as "the Grave" rather than transliterating "Hades" (ESV/NASB/NIV) or rendering "hell" (KJV). Consistent with the NWT's pattern at Rev 1:18 and 20:14, the choice supports the Watchtower's soul-sleep doctrine by collapsing Hades into the bodily burial site.
