Daniel 3:25, 27

He said, “Look! I see four men walking around in the fire, unbound and unharmed, and the fourth looks like a son of the gods.”

and the satraps, prefects, governors and royal advisers crowded around them. They saw that the fire had not harmed their bodies, nor was a hair of their heads singed; their robes were not scorched, and there was no smell of fire on them.
