Passage
And the strong shall be for tow, and his work a spark; and they shall both burn together, and there shall be none to quench [them].
And the strong shall be for tow, and his work a spark; and they shall both burn together, and there shall be none to quench [them].
Isaiah 1:29 For they shall be ashamed of the terebinths that ye have desired, and ye shall blush for the gardens that ye have chosen.
Isaiah 1:30 For ye shall be as a terebinth whose leaf fadeth, and as a garden that hath no water.
Isaiah 1:31 And the strong shall be for tow, and his work a spark; and they shall both burn together, and there shall be none to quench [them].
The verse centers on "strong", "shall", "spark", "both", "burn", and "together". It is saying that the verse draws attention to "strong" and "shall", so its meaning should be read from those terms before moving to application.
The prior verse says "For ye shall be as a terebinth...", giving immediate footing for "strong" and "shall". 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 "strong" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
