Revelation 4:2

After these things I looked and saw a door opened in heaven; and the first voice that I heard, like a trumpet speaking with me, was one saying, “Come up here, and I will show you the things which must happen after this.”

that looked like a jasper stone and a sardius. There was a rainbow around the throne, like an emerald to look at.

Around the throne were twenty-four thrones. On the thrones were twenty-four elders sitting, dressed in white garments, with crowns of gold on their heads.

Out of the throne proceed lightnings, sounds, and thunders. There were seven lamps of fire burning before his throne, which are the seven Spirits of God.
