What does Isaiah 30:33 mean?

Topheth has been ready for a long time, prepared for the king. It’s deep and wide, piled high with firewood. The Lord’s breath, like a river of burning sulfur, will set it all ablaze. Isaiah 30:33 - Modern Text Bible

(Topheth, a place of burning, is a symbol for judgment and destruction. It’s prepared for the enemy king, and God himself will ignite it.)
