The Lord continues to describe the army of Assyria as a river that will flood Judah. (See: Isaiah 8:5)

and it will sweep onward into Judah, flooding and passing on, until it reaches to the your neck

"and more and more soldiers will come like waters rising up to your neck" (See: rc://en/ta/man/translate/figs-metaphor) AT: "The army will spread out over your entire land like a bird spreading its wings over its prey."

O Immanuel

See how you translated this in Isaiah 7:13.
