Yahweh tells Ezekiel to speak to Mount Seir as if it could hear him. The message is for all of the people of Edom. Alternate translation: "Listen, Mount Seir, I will strike you with my hand and make you a desolation and a waste because of what your people did" (See: [[rc://en/ta/man/jit/figs-personification]])
The abstract noun "desolation" can be translated as an adjective. Alternate translation: "make you desolate" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
