Daniel 3:19-20

19Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abednego: therefore he spoke, and commanded that they should heat the furnace seven times more than it was heated before.1 20And he commanded the most mighty men that were in his army to bind Shadrach, Meshach, and Abednego, and to cast them into the burning fiery furnace.2
