Revelation 4:6-8 Easy-to-Read Version (ERV)
6 Also before the throne there was something that looked like a sea of glass, as clear as crystal.
In front of the throne and on each side of it there were four living beings. They had eyes all over them, in front and in back. 7 The first living being was like a lion. The second was like a bull. The third had a face like a man. The fourth was like a flying eagle. 8 Each of these four living beings had six wings. They were covered all over with eyes, inside and out. Day and night they never stopped saying,
“Holy, holy, holy is the Lord God All-Powerful.
