In Daniel 3, King Nebuchadnezzar set up an enormous image of gold and decreed that everyone should bow down to it. Daniel’s friends — Shadrach, Meshach and Abednego — refused to do so, and so were thrown into a fiery furnace which miraculously did not harm them.
Many people have wondered where Daniel was during this episode. He would not have been willing to bow down to the image either, yet he is not mentioned in chapter. We can only guess that he must have been out of town for some reason. In the previous chapter, Daniel had been made ruler of the entire province of Babylon, so he may have been on official business in another part of the province.
