Who is the Destroyer

There is a destroyer mentioned in the bible.  Check Exodus Verse 12:23. 
Of course all have heard of the Angel of Death.   She is mentioned in the bible in Exodus and she passed over the homes of the Israelites in the days of the Exodus. 
This should be quite frightening because she is very real indeed.
Her job is to preserve society. 
That which will destroy Society, the Angel of Death will destroy herself.
Think about that when you are up late at night.
