His empire shall be multiplied, and there shall be no end of peace: he shall sit upon the throne of David, and upon his kingdom; to establish it and strengthen it with judgment and with justice, from henceforth and for ever: the zeal of the Lord of hosts will perform this.
Isaiah 9:5 For every violent taking of spoils, with tumult, and garment mingled with blood, shall be burnt, and be fuel for the fire.
Isaiah 9:6 For a CHILD IS BORN to us, and a son is given to us, and the government is upon his shoulder: and his name shall be called Wonderful, Counsellor, God the Mighty, the Father of the world to come, the Prince of Peace.
Isaiah 9:7 His empire shall be multiplied, and there shall be no end of peace: he shall sit upon the throne of David, and upon his kingdom; to establish it and strengthen it with judgment and with justice, from henceforth and for ever: the zeal of the Lord of hosts will perform this.
Isaiah 9:8 The Lord sent a word into Jacob, and it hath lighted upon Israel.
Isaiah 9:9 And all the people of Ephraim shall know, and the inhabitants of Samaria that say in the pride and haughtiness of their heart:
The verse centers on "empire", "shall", "multiplied", "peace", "upon", and "throne". It is saying that the verse draws attention to "empire" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "For a CHILD IS BORN to us..." into verse 8's "The Lord sent a word into Jacob...", so "empire" 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 "empire" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
