Daniel 3:19-20

3:19 Then Nebuchadnezzar was filled with rage, and his disposition changed toward Shadrach, Meshach, and Abednego. He gave orders to heat the furnace seven times hotter than it was normally heated. 3:20 He ordered strong soldiers in his army to tie up Shadrach, Meshach, and Abednego and to throw them into the furnace of blazing fire.
