Revelation 4:3 in the World English Bible
that looked like a jasper stone and a sardius. There was a rainbow around the throne, like an emerald to look at.
Context
2 And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne.
3 And he that sat was to look upon like a jasper and a sardine stone: and there was a rainbow round about the throne, in sight like unto an emerald.
4 And round about the throne were four and twenty seats: and upon the seats I saw four and twenty elders sitting, clothed in white raiment; and they had on their heads crowns of gold.
