'Linen' in the Bible

I lifted up my eyes to look, and to my surprise, there was a certain man dressed in linen, whose waist was encircled with gold from Uphaz!

One asked the man dressed in linen clothes, who was standing above the waters of the river, "How long until the fulfillment of the wonders?'

"I heard the man dressed in linen clothes, who was standing above the waters of the river as he lifted his right and left hands to heaven and swore by the one who lives forever that it would be for a time, times, and a half. When the shattering of the power of the holy people has occurred, all these things will conclude."
