But there shall be no gloom to her that was in anguish. In the former time he brought into contempt the land of Zebulun and the land of Naphtali; but in the latter time hath he made it glorious, by the way of the sea, beyond the Jordan, Galilee of the nations.
Isaiah 9:1 But there shall be no gloom to her that was in anguish. In the former time he brought into contempt the land of Zebulun and the land of Naphtali; but in the latter time hath he made it glorious, by the way of the sea, beyond the Jordan, Galilee of the nations.
Isaiah 9:2 The people that walked in darkness have seen a great light: they that dwelt in the land of the shadow of death, upon them hath the light shined.
Isaiah 9:3 Thou hast multiplied the nation, thou hast increased their joy: they joy before thee according to the joy in harvest, as men rejoice when they divide the spoil.
The verse centers on "shall", "gloom", "anguish", "former", "time", "brought", "contempt", and "land". It is saying that the verse draws attention to "shall" and "gloom", so its meaning should be read from those terms before moving to application.
The next verse adds "The people that walked in darkness have...", so "shall" and "gloom" should be read forward into that movement. 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 "shall" and "gloom" with trust shaped by these words, not by a vague optimism outside the passage.
