Revelation 4:6-11 (NKJV)
6 Before the throne there was a sea of glass, like crystal. And in the midst of the throne, and around the throne, were four living creatures full of eyes in front and in back.
7 The first living creature was like a lion, the second living creature like a calf, the third living creature had a face like a man, and the fourth living creature was like a flying eagle.
8 The four living creatures, each having six wings, were full of eyes around and within. And they do not rest day or night, saying: “Holy, holy, holy, Lord God Almighty, Who was and is and is to come!”
9 Whenever the living creatures give glory and honor and thanks to Him who sits on the throne, who lives forever and ever,
10 the twenty-four elders fall down before Him who sits on the throne and worship Him who lives forever and ever, and cast their crowns before the throne, saying:
11 “You are worthy, O Lord, To receive glory and honor and power; For You created all things, And by Your will they exist and were created.”
