Daniel 3:19-27 NASB
19 Then Nebuchadnezzar was filled with wrath, and his facial expression was altered toward Shadrach, Meshach and Abed-nego. He answered by giving orders to heat the furnace seven times more than it was usually heated. 20 He commanded certain valiant warriors who were in his army to tie up Shadrach, Meshach and Abed-nego in order to cast them into the furnace of blazing fire. 21 Then these men were tied up in their trousers, their coats, their caps and their other clothes, and were cast into the midst of the furnace of blazing fire. 22F or this reason, because the king's command was urgent and the furnace had been made extremely hot, the flame of the fire slew those men who carried up Shadrach, Meshach and Abed-nego. 23 But these three men, Shadrach, Meshach and Abed-nego, fell into the midst of the furnace of blazing fire still tied up.
24 Then Nebuchadnezzar the king was astounded and stood up in haste; he said to his high officials, "Was it not three men we cast bound into the midst of the fire?" They replied to the king, "Certainly, O king." 25 He said, "Look! I see four men loosed and walking about in the midst of the fire without harm, and the appearance of the fourth is like a son of the gods!" 26 Then Nebuchadnezzar came near to the door of the furnace of blazing fire; he responded and said, "Shadrach, Meshach and Abed-nego, come out, you servants of the Most High God, and come here!" Then Shadrach, Meshach and Abed-nego came out of the midst of the fire. 27 The satraps, the prefects, the governors and the king's high officials gathered around and saw in regard to these men that the fire had no effect on the bodies of these men nor was the hair of their head singed, nor were their trousers damaged, nor had the smell of fire even come upon them.
