Daniel 3:19-20

Upon hearing this, Nebuchadnezzar was filled with anger, and his face was distorted with rage against Shadrach, Meshach, and Abednego. He ordered his men to heat the fiery furnace seven times hotter than it usually was. He also commanded some of his mighty men to bind Shadrach, Meshach, and Abednego and throw them into the white-hot furnace.
