What lies did the Nazis first use to trick Jews into concentration camps?

This is very simple, because the Nazis lied to the Jews about changing their residence, then transported them to the concentration camp by train in batches, and then lied to the Jews to take a bath in the gas chamber (note: the gas chamber has been disguised as an ordinary bathroom, and it is impossible to see that it is a gas chamber). In order to convince the Jews, they allowed them to bring something in, pretending that they just wanted to clean themselves. When the Jews came in, the Nazis closed the door and put poison gas in it to kill them.
