Shadrach, Meshach and Abednego
During his rule, King Nebuchadnezzar of Babylon built a gigantic gold statue and insisted that all his subjects worship it, threatening that anyone who disobeyed would be thrown into a fiery furnace.
While most of the populace promptly obeyed, three young men — friends of Daniel — named Shadrach, Meschach and Abednego refused, because they worshipped only one God.
Nebuchadnezzar was furious and summoning the three men offered them a last chance to bow down before his statue or be hurled into the furnace. "Then what god will be able to rescue you from my hand?" he mocked.
Shadrach, Meshach and Abednego replied to the king, "O Nebuchadnezzar, we do not need to defend ourselves before you in this matter. If we are thrown into the blazing furnace, the God we serve is able to save us from it, and he will rescue us from your hand, O king. But even if he does not, we want you to know, O king, that we will not serve your gods or worship the image of gold you have set up." (Daniel 3:16-18)
This only made the king angrier and he ordered the furnace to be made seven times hotter. So fierce were the flames that the soldiers who threw the three men into the fire were themselves burnt to death immediately. The king expected to see the three burnt to a cinder but to his amazement, not only did he see the three men standing unruffled, he saw a fourth man there too. Awed, he asked the three men to come out.
Shadrach, Meschach and Abednego walked out. Their bodies and clothes and not been burned at all. They didn't even smell of smoke.
Then Nebuchadnezzar said, "Praise be to the God of Shadrach, Meshach and Abednego, who has sent his angel and rescued his servants! They trusted in him and defied the king's command and were willing to give up their lives rather than serve or worship any god except their own God. Therefore I decree that the people of any nation or language who say anything against the God of Shadrach, Meshach and Abednego be cut into pieces and their houses be turned into piles of rubble, for no other god can save in this way."
And the king promoted them to higher jobs in the kingdom.
