The thrice-holy worship takes us back to Isaiah 6:3, an obvious divine council scene. Other points of similarity to other council visions include the creatures (cf. description of cherubim in Ezek 1; 10); wings on the creatures (cf. seraphim of Isa 6); God enthroned (Isa 6; Ezek 1; Dan 7), multiple thrones (Dan 7); the gemstones, colors, and sea of glass (Ezek 1); divine spirits (1 Kgs 22). John’s vision in fact combines earlier divine council features in this one vision.
