Jesus explains with a parable why it is foolish for people to think that Jesus is controlled by Satan. (See: [[rc://en/ta/man/translate/figs-parables]])
Jesus asked this rhetorical question in response to the scribes saying that he cast out demons by Beelzebul. This question can be written as a statement. AT: "Satan cannot cast out himself!" or "Satan does not go against his own evil spirits!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
