Divine anger and punishment are never random; they arrive as a direct result of the people's betrayal. A clear line of cause and effect is established, showing that the impending consequences fall upon them simply because they abandoned God. Their central failure was an act of profound disloyalty, as they chose to offer sacrifices to other gods.
In response to this betrayal, God's anger is sparked and burns intensely within that specific place. This divine reaction is like a fire that cannot be put out. The flames of His anger will not be extinguished, emphasizing that the severe consequences of their actions will not fade away or cease.
