What does Isaiah 7:7 mean?
The Lord has sent Isaiah to give a message to King Ahaz of Judah: do not be terrified of the kings of Syria and Israel. These kings are coming to remove him from his throne, but the Lord instructs him to not be afraid. Specifically, Isaiah is to tell Ahaz to be calm (Isaiah 7:4).Now the Lord begins to reveal why Ahaz doesn't have to be afraid of these two seemingly powerful kings and their evil plans for him. Their scheme will fail (Isaiah 7:5–6). In fact, the Lord says their plan will not even come to pass.
Delivering this prophecy from the Lord, Isaiah returns for these few verses to using the familiar form of poetry (Isaiah 7:8–9). This is the format which filled much of the first six chapters of his book.
