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 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 12:10

12:10 Then I heard a loud voice in heaven saying,

“The salvation and the power

and the kingdom of our God,

and the ruling authority of his Christ, have now come,

because the accuser of our brothers and sisters,

the one who accuses them day and night before our God,

has been thrown down.
