Passage
And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err.
And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err.
Isaiah 30:26 Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound.
Isaiah 30:27 Behold, the name of the LORD cometh from far, burning with his anger, and the burden thereof is heavy: his lips are full of indignation, and his tongue as a devouring fire:
Isaiah 30:28 And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err.
Isaiah 30:29 Ye shall have a song, as in the night when a holy solemnity is kept; and gladness of heart, as when 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 cause his glorious voice to be heard, and shall shew the lighting down of his arm, with the indignation of his anger, and with the flame of a devouring fire, with scattering, and tempest, and hailstones.
The verse centers on "breath", "overflowing", "stream", "shall", "reach", "midst", "neck", and "sift". It is saying that the verse draws attention to "breath" and "overflowing", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 27's "Behold the name of the LORD cometh..." into verse 29's "Ye shall have a song as in...", so "breath" and "overflowing" 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 "breath" and "overflowing" with trust shaped by these words, not by a vague optimism outside the passage.
