This picture showes how everyone felt while they were in the concentration camps. When they would get beat or see someone get beat they didn't say anything they were silent because they didn't want to get into trouble by saying something or be beat more. Silence plays a big role in the book. Everyone was silent, they didn't stand up for themsevles, or others and god was a part of the silence. No one knew why god was keeping silent when all this was happining to them, the people that worshiped him.
