Revelation 4:6-8

Riverside(i) 6 Before the throne there was as it were a glassy sea, like crystal. Near the throne and around the throne there were four living creatures full of eyes before and behind. 7 The first living creature was like a lion, the second living creature was like a calf, the third living creature had a face like a man's, and the fourth living creature was like a flying eagle. 8 The four living creatures have each six wings, and around and within they are full of eyes. They cease not saying day and night, "Holy, holy, holy is the Lord God Almighty, who was and is and is to come."
