Thematic Bible: The four living creatures

And before the seat there was a sea of glass, like unto crystal, and in the midst of the seat, and round about the seat, were four beats full of eyes before and behind. And the first beast was like a lion, the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle. And the four beasts had, each one of them, six wings about him, and they were full of eyes within. And they had no rest day neither night saying, "Holy, holy, holy, Lord God almighty, which was, and is, and is to come."
