"And immediately I was in the spirit: and, behold a Throne was set in Heaven, and One sat on the Throne.
And He that sat was to look upon like Jasper and a Sardius stone: and there was a Rainbow round about the Throne, in sight like unto an Emerald.

And out of the Throne proceeded Lightnings and Thunderings and Voices; and there were Seven Lamps of Fire burning before the Throne, which are the Seven Spirits of God.
And before the Throne there was a Sea of Glass like unto Crystal."
Revelation 4:2-3, 5-6
