Explain the rhetorical strategy used in the following line "thus passed the year 1943" in Wiesel's novel Night.

The phrase happens early on in the narrative.  This brings
to light that much of what will happen in the book in terms of what is experienced is
going to test how one views time.  That is to say that what Eliezer deems as time
"passed" will be vastly different as the book progresses.  From a thematic point of
view, the point at which Eliezer uses the phrase, Moshe the Beadle has lived through his
own hell and has come back to Sighet to warn the other townspeople of what is in store
for them.  He is greeted with mocking derision and disbelief.  Discredited and rejected,
Moshe recognizes that his cries and warnings are falling upon the deaf ears of people
who go back to their routines.  For his part, Eliezer goes back to his studies and his
father "took care of his business and the community" and "worrying about an appropriate
match for Hilda."  Life passes on without so much as a thought or secondary impulse that
a fraction of what Moshe is saying is or could be true.  The rhetorical use of the
phrase is to bring to light that the insensitivity that was shown to victims of the
Holocaust was first perpetrated amongst one another.  In this light, one real tragic
condition of the Holocaust was that individuals demonstrated the invalidation of
humanity to one another, as it was appropriated by the victims of aggression to one
another.  The fact that the year passes without any recollection or serious rumination
about reports brings this idea out that the Holocaust was the result of an invalidation
of voices from all perspectives.
