Revelation 5:13-14

13And I heard every created thing that is in heaven or on earth or under the earth [in Hades, the realm of the dead] or on the sea, and everything that is in them, saying [together], “To Him who sits on the throne, and to the Lamb (Christ), be blessing and honor and glory and dominion forever and ever.”

14And the four living creatures kept saying, “Amen.” And the elders fell down and worshiped [Him who lives forever and ever].
