Daniel 3:19-20

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 commanded certain strong men in his army to tie up Shadrach, Meshach, and Abed-nego and to throw them into the furnace of blazing fire.
