'Robes' in the Bible

Therefore I counsel you to buy of Me gold refined in the fire that you may become rich, and white robes to put on, so as to hide your shameful nakedness, and eye-salve to anoint your eyes with, so that you may be able to see.

Surrounding the throne there were also twenty-four other thrones, on which sat twenty-four Elders clothed in white robes, with victors' wreaths of gold upon their heads.

After this I looked, and a vast host appeared which it was impossible for anyone to count, gathered out of every nation and from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in long white robes, and carrying palm-branches in their hands.

Then, addressing me, one of the Elders said, "Who are these people clothed in the long white robes? And where have they come from?"

"My lord, you know," I replied. "They are those," he said, "who have just passed through the great distress, and have washed their robes and made them white in the blood of the Lamb.

Blessed are those who wash their robes clean, that they may have a right to the Tree of Life, and may go through the gates into the city.
