Revelation 4:7-8

4:7 The first living creature was like a lion, the second creature like an ox, the third creature had a face like a man’s, and the fourth creature looked like an eagle flying. 4:8 Each one of the four living creatures had six wings and was full of eyes all around and inside. They never rest day or night, saying:

“Holy Holy Holy is the Lord God, the All-Powerful,

Who was and who is, and who is still to come!”
