Revelation 4:6-8

6and before the throne there was something like a 1sea of glass, like crystal; and in the 2center and 3around the throne, 4four living creatures 5full of eyes in front and behind.

76The first living creature was like a lion, the second creature like a calf, the third creature had a face like that of a man, and the fourth creature was like a flying eagle.

8And the 7four living creatures, each one of them having 8six wings, are 9full of eyes around and within; and 10day and night 11they do not cease to say, “12Holy, holy, holy is the 13Lord God, the Almighty, 14who was and who is and who 15is to come.”
