How in a moment they will become a horror!
They come to an end—they perished by destructive events. Bible

“they perished.” This is the prophetic perfect idiom; they will perish. They have not perished yet, but they will. [For more on the prophetic perfect, see commentary on Eph. 2:6].

“by destructive events.” The Hebrew is more literally, “by terrors,” where “terrors” is put by metonymy for things which cause terror, such as disaster.
