Refusing to believe that Yahweh will cause disaster is spoken of as if the "day of disaster" were an object the people could put far from themselves. Alternate translation: "to those who refuse to believe that I will cause them to experience disaster" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Here "throne" is a metonym that represents reign or rule. The people doing evil things, which causes Yahweh to bring disaster on them, is spoken of as if they were causing "violence" to rule them. Alternate translation: "but who are actually causing me to send violent people to destroy you" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-metaphor]])
