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. Then Nebuchadnezzar came near to the mouth of the burning fiery furnace: he spake and said, Shadrach, Meshach, and Abed-nego, ye servants of the Most High God, come forth, and come hither. Then Shadrach, Meshach, and Abed-nego came forth out of the midst of the fire. 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.
