[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. [15] Therefore before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
