 Then I looked, and I heard the voices of many angels around the throne, and the four living creatures, and the elders. There were thousands and thousands of angels,  saying in a loud voice: Then I heard all creatures in heaven and on earth and under the earth and in the sea saying: The four living creatures said, “Amen,” and the elders bowed down and worshiped. – Revelation 5:11-14 http://www.biblegateway.com/passage/?search=Revelation5:11-14&version=NCV
