'Damaged' in the Bible

He made answer and said, Look! I see four men loose, walking in the middle of the fire, and they are not damaged; and the form of the fourth is like a son of the gods.

The satraps, the prefects, the governors and the king’s high officials gathered around and saw in regard to these men that the fire had no effect on the bodies of these men nor was the hair of their head singed, nor were their trousers damaged, nor had the smell of fire even come upon them.
