Shadrach, Meshach, and Abednego are three men from the Bible story in Daniel 3, who were thrown into a fiery furnace by King Nebuchadnezzar of Babylon because they refused to worship a golden statue, demonstrating their unwavering faith in God even in the face of extreme danger; they emerged unharmed from the fire, leading the king to praise their God.
