Aside from Moshe the Beadle's stories (which is the biggest example and goes mostly ignored by everyone), there are a few other things that happened before the town was shipped off to concentration camps. It is important to note that all the while, by following directions and listening to orders they BELIEVED they would be ok.
First, people were moved out of their houses and relocated block by block to other houses. This new organization of people was of course known as the "ghettos." The synagogue was closed down and they were forced to worship privately or in their homes. They had to hand over their valuables (and many burried personal items).
Ironically, through all of these signs, Wiesel is pretty clear that the enormity of the situation didn't hit most of them until they were packed into cattle cars and shipped off by the 100s.
The opening pages detailing Moshe the Beadle might help to illuminate much about the attitude of those in Sighet to what lies ahead. Moshe is expelled from the village, taken by the Nazis to a forest, made to dig trenches or mass graves, and then sees people being shot one by one. He was shot in the leg and pretends to be dead. He sees horrific realities and is convinced that he must go back to the people of Sighet and warn them about what is to come. He becomes driven to warn others and when he tells his tale, the villagers deny it and essentially dismiss him. They dehumanize him by suggesting that Moshe wants money or attention. It is in this act of disbelief and rejection that Wiesel suggests that one of the most striking elements of the Holocaust was how victims treated one another. Rather than experience the complete bonds of collectivity in an instant, this is a condition where individuals doubt one another and a mistrust due to internal aloneness ends up resulting. It is with this in mind, that the early stages of resistance demonstrated by Moshe the Beadle is rebuked. Moshe leaves a broken man, not for what happened to him, bur rather what will happen to those in Sighet.
