This chapter Isaiah 9 is a continuation of the prophecy begun in Isaiah 7, and continued in Isaiah 8. It is composed of mingled threats and promises. Its characteristic may be said to be “rays of light thrown into the midst of shades.” It promises comfort and deliverance, while at the same time it denounces the sins of the nation, and assures the nation that the anger of the Lord is not turned away. The previous chapter had closed by describing a time of general calamity and darkness. This begins Isaiah 9:1-4 by showing that the calamity would not be so great as in former times. It would be mitigated. There would be light - particularly in the dark regions of Zebulun and Naphtali - the provinces lying most exposed to the Syrian invasion. This light or deliverance was connected with the birth of the promised child Isaiah 9:6-7; and the mention of this leads the prophet into a magnificent description of his names, character, and reign. The prophet then returns to the threatened destruction of Israel and denounces the divine judgment against it. By the Syrians and the Philistines it would be invaded and destroyed, Isaiah 9:8-12. The effects of this, in cutting off their sources of strength, and producing general dismay and ruin, are described in the remainder of the chapter, Isaiah 9:13-21. The chapter, therefore, would impart consolation to the inhabitants of Judah, and is designed to confirm the promise that it should be safe from the threatened invasion; compare Isaiah 8:1-4.
