Daniel 3:23-25

23And these three men, Shadrach, Meshach, and Abed–nego, fell down bound into the midst of the burning fiery furnace.

24Then Nebuchadnezzar the king was astonied, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king.1

25He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God.2
