Daniel 3:16-19

Shadrach, Meshach, and Abed-nego answered and said to the king, O Nebuchadnezzar, we have no need to answer thee in this matter. If it be so, our God whom we serve is able to deliver us from the burning fiery furnace; and he will deliver us out of thy hand, O king. But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up. Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abed-nego: therefore he spake, and commanded that they should heat the furnace seven times more than it was wont to be heated.
