For those who follow Yahweh, he is a sanctuary from the perils of the world. However, to those who ignore his warnings he is an obstacle in their path. His will cannot be denied. It will either save or damn. If Judah denies the prophetic warning, it will become a snare in which Jerusalem will be caught by the invading army of Assyria. Poetically, Isaiah heaps up the catalog of calamities: they will stumble, fall, be broken, be snared, and be taken.
