Daniel 3:19-20

Then Nebuchadnezzar was filled with fury, and the expression of his face was changed against Shadrach, Meshach, and Abednego. He ordered the furnace heated seven times more than it was usually heated. And he ordered some of the mighty men of his army to bind Shadrach, Meshach, and Abednego, and to cast them into the burning fiery furnace.
