'Hair' in the Bible

And the princes, governors, and captains, and the king's counsellers, being gathered together, saw these men, upon whose bodies the fire had no power, nor was an hair of their head singed, neither were their coats changed, nor the smell of fire had passed on them.

At that moment the sentence against Nebuchadnezzar was executed. He was driven away from people. He ate grass like cattle, and his body was drenched with dew from the sky, until his hair grew like eagles’ feathers and his nails like birds’ claws.

I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire.
