Passage
And Jehovah will cause the majesty of his voice to be heard, and will shew the lighting down of his arm with indignation of anger, and a flame of consuming fire, with waterflood and storm and hailstones.
And Jehovah will cause the majesty of his voice to be heard, and will shew the lighting down of his arm with indignation of anger, and a flame of consuming fire, with waterflood and storm and hailstones.
Isaiah 30:28 and his breath as an overflowing torrent, which reacheth even to the neck, to sift the nations with the sieve of destruction, and [to put] a bridle into the jaws of the peoples, that causeth them to go astray.
Isaiah 30:29 Ye shall have a song, as in the night when a feast is sanctified; and joy of heart, as of one who goeth with a pipe to come unto the mountain of Jehovah, to the Rock of Israel.
Isaiah 30:30 And Jehovah will cause the majesty of his voice to be heard, and will shew the lighting down of his arm with indignation of anger, and a flame of consuming fire, with waterflood and storm and hailstones.
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.
The verse centers on "light", "jehovah", "cause", "majesty", "voice", "heard", "shew", and "lighting". It is saying that the verse draws attention to "light" and "jehovah", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "Ye shall have a song as in..." into verse 31's "For through the voice of Jehovah shall...", so "light" and "jehovah" 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 "light" and "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
