What does Hannah tell the Rabbi to try to get him to turn around?

Hannah tells the Rabbi that six million Jews will be killed by the Nazis.

"The men down there," she cried out desperately, "they're not wedding guests. They're Nazis. Nazis! Do you understand? They kill people. They killed—kill— will kill Jews. Hundreds of them. Thousands of them. Six million of them! I know. Don't ask me how I know, I just do. We have to turn the wagons around. We have to run!"
