Passage
And the Lord shall make the glory of his voice to be heard, and shall shew the terror of his arm, in the threatening of wrath, and the flame of devouring fire: he shall crush to pieces with whirlwind, and hailstones.
And the Lord shall make the glory of his voice to be heard, and shall shew the terror of his arm, in the threatening of wrath, and the flame of devouring fire: he shall crush to pieces with whirlwind, and hailstones.
Isaiah 30:28 His breath as a torrent overflowing even to the midst of the neck, to destroy the nations unto nothing, and the bridle of error that was in the jaws of the people.
Isaiah 30:29 You shall have a song as in the night of the sanctified solemnity, and joy of heart, as where one goeth with a pipe, to come into the mountain of the Lord, to the Mighty One of Israel.
Isaiah 30:30 And the Lord shall make the glory of his voice to be heard, and shall shew the terror of his arm, in the threatening of wrath, and the flame of devouring fire: he shall crush to pieces with whirlwind, and hailstones.
Isaiah 30:31 For at the voice of the Lord the Assyrian shall fear being struck with the rod.
Isaiah 30:32 And the passage of the rod shall be strongly grounded, which the Lord shall make to rest upon him with timbrels and harps, and in great battles he shall overthrow them.
The verse centers on "lord", "shall", "make", "glory", "voice", "heard", and "shew". It is saying that the verse draws attention to "lord" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "You shall have a song as in..." into verse 31's "For at the voice of the Lord...", so "lord" and "shall" 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 "lord" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
