Revelation 4:2-6

At once I was in [special communication with] the Spirit; and behold, a throne stood in heaven, with One seated on the throne. [Ezek 1:26] And He who sat there appeared like [the crystalline sparkle of] a jasper stone and [the fiery redness of] a sardius stone, and encircling the throne there was a rainbow that looked like [the color of an] emerald. [Ezek 1:28; Rev 21:11, 19] Twenty-four [other] thrones surrounded the throne; and seated on these thrones were twenty-four elders dressed in white clothing, with crowns of gold on their heads. From the throne came flashes of lightning and [rumbling] sounds and peals of thunder. Seven lamps of fire were burning in front of the throne, which are the seven Spirits of God; [Ex 19:16-20a] and in front of the throne there was something like a sea or large expanse of glass, like [the clearest] crystal. In the center and around the throne were four living creatures who were full of eyes in front and behind [seeing everything and knowing everything that is around them]. [Ps 99:1; Is 6:2, 3; Ezek 1:5, 18]
