Revelation 4:1 YLT

¹  After these things I saw, and lo, a door opened in the heaven, and the first voice that I heard 'is' as of a trumpet speaking with me, saying, 'Come up hither, and I will shew thee what it behoveth to come to pass after these things;'

²  and immediately I was in the Spirit, and lo, a throne was set in the heaven, and upon the throne is 'one' sitting,

³  and He who is sitting was in sight like a stone, jasper and sardine: and a rainbow was round the throne in sight like an emerald.
