Revelation 4:8

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!”

Revelation 5:6

5:6 Then I saw standing in the middle of the throne and of the four living creatures, and in the middle of the elders, a Lamb that appeared to have been killed. He had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.

Revelation 5:8

5:8 and when he had taken the scroll, the four living creatures and the twenty-four elders threw themselves to the ground before the Lamb. Each of them had a harp and golden bowls full of incense (which are the prayers of the saints).

Revelation 6:6

6:6 Then I heard something like a voice from among the four living creatures saying, “A quart of wheat will cost a day’s pay and three quarts of barley will cost a day’s pay. But do not damage the olive oil and the wine!”

Revelation 14:3

14:3 and they were singing a new song before the throne and before the four living creatures and the elders. No one was able to learn the song except the one hundred and forty-four thousand who had been redeemed from the earth.
