Passage
And every blow of the appointed staff, Which Yahweh will cause to rest upon him, Will be with the music of tambourines and lyres; And in battles, waving weapons He will fight them.
And every blow of the appointed staff, Which Yahweh will cause to rest upon him, Will be with the music of tambourines and lyres; And in battles, waving weapons He will fight them.
Isaiah 30:30 And Yahweh will cause His splendid voice to be heard, And the descending of His arm to be seen in raging anger, And in the flame of a consuming fire In cloudburst, downpour, and hailstones.
Isaiah 30:31 For at the voice of Yahweh Assyria will be dismayed, When He strikes with the rod.
Isaiah 30:32 And every blow of the appointed staff, Which Yahweh will cause to rest upon him, Will be with the music of tambourines and lyres; And in battles, waving weapons He will fight them.
Isaiah 30:33 For Topheth has long been ready, Indeed, it has been prepared for the king. He has made it deep and large, A pyre of fire with plenty of wood; The breath of Yahweh, like a torrent of brimstone, sets it afire.
The verse centers on "blow", "appointed", "staff", "yahweh", "cause", "rest", "upon", and "music". It is saying that the verse draws attention to "blow" and "appointed", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 31's "For at the voice of Yahweh Assyria..." into verse 33's "For Topheth has long been ready Indeed...", so "blow" and "appointed" belong inside that flow. 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 "blow" and "appointed" with trust shaped by these words, not by a vague optimism outside the passage.
