And the first creature was like a lion, and the second creature like a calf, and the third creature had a face like that of a man, and the fourth creature was like a flying eagle. And the four living creatures, each one of them having six wings, are full of eyes around and within; and day and night they do not cease to say, “Holy, holy, holy, is the Lord God, the Almighty, who was and who is and who is to come.” Revelation 4:8 (NAS)
