The Revelation 4:2-4

Immediately I was in the Ruach; and behold, a throne was standing in heaven, and One seated on the throne. And the One who was seated was like jasper and carnelian in appearance, and a rainbow around the throne, like an emerald in appearance. Around the throne were twenty-four thrones, and seated on the thrones were twenty-four elders dressed in white clothes with golden crowns on their heads.
