'White' in the Bible

In that very hour the fingers of a man's hand were seen, writing opposite the support for the light on the white wall of the king's house, and the king saw the part of the hand which was writing.

I went on looking till the seats of kings were placed, and one like a very old man took his seat: his clothing was white as snow, and the hair of his head was like clean wool; his seat was flames of fire and its wheels burning fire.
