Daniel 3:25, 27

He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the aspect of the fourth is like a son of the gods.

And the satraps, the deputies, and the governors, and the king’s counsellors, being gathered together, saw these men, that the fire had no power upon their bodies, nor was the hair of their head singed, neither were their hosen changed, nor had the smell of fire passed on them.
