Daniel 3:19-20

Then Nebuchadnezzar was full of fury, and the expression on his face changed toward Shadrach, Meshach, and Abed-Nego. He spoke and commanded that they heat the furnace seven times more than it was usually heated. And he commanded certain mighty men of valor who were in his army to bind Shadrach, Meshach, and Abed-Nego, and cast them into the burning fiery furnace.
