When Jesus spoke again to the people, he said, “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”
Then I looked and heard the voice of many angels, numbering thousands upon thousands, and then thousand times ten thousand. They encircled the throne and the living creatures and the elders. In a loud voice they sang:
Then I heard every creature in heaven and on earth and under the earth and on the sea, and all that is in them, singing:
The four living creatures said "Amen," and the elders fell down and worshiped.
