The four and twenty elders (hoi eikosi tessares presbuteroi). They follow the living creatures (Rev 11:15, if correctly interpreted) in their adoration, as in Rev 4:9. Though seated on thrones of their own (Rev 4:4), yet they fall upon their faces in every act of worship to God and Christ (Rev 4:10; Rev 5:8, Rev 5:14; Rev 19:4). Here epi ta prosōpa autōn (upon their faces) is added as in Rev 7:11 about the angels. The elders here again represent the redeemed, as the four living creatures the forces of nature, in the great thanksgiving here (eucharistoumen, present active indicative of eucharisteō).
