6.2. Diadema

The Greek word for crown is διάδημα [diadēma] in the following passages:
  1. Crowns on the seven heads of the fiery red dragon (Rev. Rev. 12:3+).
  2. Crowns on the ten horns of the beast rising up from the sea (Rev. Rev. 13:1+).
  3. Crowns upon the head of the one called Faithful and True (Rev. Rev. 19:12+).
The “royal crown” is found upon the head of Jesus in only one passage. In the other two passages, it is upon the heads of the enemies of God.
