Revelation 19

Speaking of the righteous and His second coming, John writes -

"Let us be glad and rejoice, and give honour to him: for the marriage of the Lamb is come, and his wife hath made herself ready.
8 And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints."  (Revelation 19:7–8)

As well as -

"And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean."  (Revelation 19:14)

I couldn't help but think of the righteous that serve in the temple...linen white and clean.
