This is the first occurrence of the words ^abomination^ and ^desolation^ in the same passage.
It lays out the basic understanding of the phrase: AbominationThatMakesDesolate.
Specifically, it connects gross wickedness (abominations) with the extreme destruction (desolation) of a people, their culture, their government and, ultimately, their sovereignty.
That which was once glorious has become an astonishment to those who observe its fall from grandeur to nothingness.
