Daniel 3:19, 25

Then Nebuchadnezzar was filled with fury, and his facial expression changed toward Shadrach, Meshach, and Abed-nego. Then he gave a command that the furnace was to be heated seven times hotter than usual.

He answered, “Look! I see four men untied, walking around in the midst of the fire, and they are not hurt! And the appearance of the fourth is like a son of the gods!” [Phil 2:5-8]
