[11] And all the angels stood round about the throne, and about the elders and the four beasts, and fell before the throne on their faces, and worshipped God, [12] Saying, Amen: Blessing, and glory, and wisdom, and thanksgiving, and honour, and power, and might, God for ever Amen. [13] And one of the elders answered, saying What these which are arrayed in white robes? and whence came they? [14] And I said unto him, Sir, thou knowest. And he said These which came out of great tribulation, and have washed their robes, and them white in the blood of the Lamb.
