Daniel 3:23-25 NIV

23 and these three men, firmly tied, fell into the blazing furnace.
24 Then King Nebuchadnezzar leaped to his feet in amazement and asked his advisers, "Weren't there three men that we tied up and threw into the fire?" They replied, "Certainly, O king."
25 He said, "Look! I see four men walking around in the fire, unbound and unharmed, and the fourth looks like a son of the gods."
