The angelic proclamation--7:11-12.
In the acknowledgment of this salvation all of the angels were standing about the throne and about the twenty-four elders and the four creature-beings. Together encircling the throne they prostrated their angelic forms before it, and said Amen, to the voice of the multitude which had ascribed salvation unto God and unto the Lamb.
Reference to “ all the angels” does not mean all angels in heaven, but all the angels in this vision, beginning in the fourth chapter. After saying Amen to the acknowledgments of salvation by the multitude, they repeated the doxology of chapter 5:12, with the exception of the omission of “ riches,” inserting thanksgiving and substituting might for “ strength.” For comments on the seven-fold attributes thus ascribed to God and to the Lamb refer to Revelation 5:11-13.
