How did Nazis brainwash Germans?

Before and during World War II, the Nazis tricked the Jews in Germany and elsewhere in multiple ways. Perhaps most sinister of all, they often assured the Jews being boarded on trains headed for concentration camps that the destination was going to be temporary and/or for their benefit. To this end, they advised the Jews to pack important belongings and extra clothing -- when, in actual fact, those possessions would be seized upon arrival, with the Jews themselves being immediately put to death or cruelly imprisoned without hope of release.
