New Defender's Study Bible Notes
8:8 O Immanuel. The prophecy of the coming virgin-born son indicated His name would be Immanuel. In this verse, the prophecy is added that the land that would be invaded and badly damaged by the Assyrians actually belonged, not just to Israel or Judah, but to Immanuel (“God with us”). It must, therefore, eventually be redeemed and restored to its divinely intended purpose.
