Passage
For Topheth is prepared of old; for the king also it is prepared: he hath made it deep and large; its pile is fire and much wood; the breath of Jehovah, like a stream of brimstone, doth kindle it.

Isaiah 30:31 For through the voice of Jehovah shall the Assyrian be broken down: he will smite [him] with the rod.
Isaiah 30:32 And wherever shall pass the appointed staff, which Jehovah shall lay upon him, it shall be with tambours and harps; and with tumultuous battles will he fight with it.
Isaiah 30:33 For Topheth is prepared of old; for the king also it is prepared: he hath made it deep and large; its pile is fire and much wood; the breath of Jehovah, like a stream of brimstone, doth kindle it.
The verse centers on "topheth", "prepared", "king", "hath", "deep", "large", and "pile". It is saying that the verse draws attention to "topheth" and "prepared", so its meaning should be read from those terms before moving to application.
The prior verse says "And wherever shall pass the appointed staff...", giving immediate footing for "topheth" and "prepared". In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "topheth" and "prepared" with trust shaped by these words, not by a vague optimism outside the passage.
