Revelation 19:1, 5-6

After these things I heard as it were a great voice of a great multitude in heaven, saying, Hallelujah; Salvation, and glory, and power, belong to our God

And a voice came forth from the throne, saying, Give praise to our God, all ye his servants, ye that fear him, the small and the great. And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunders, saying, Hallelujah: for the Lord our God, the Almighty, reigneth.
