Final answer:
Jesus questioned the Pharisees' logic by asking who their people drove out demons by if they accused Him of casting out demons through Beelzebul, highlighting the contradiction in their reasoning.
Step-by-step explanation:
The question Jesus asked about the Pharisees casting out demons is not directly mentioned in the verses provided. However, in the context of Scriptural accounts, it is known that Jesus addressed the criticism of Pharisees regarding exorcism when they accused Him of casting out demons by the power of Beelzebul. In response, Jesus questioned the logic of their accusation by asking, 'If I drive out demons by Beelzebub, by whom do your people drive them out?' (Matthew 12:27). This was meant to highlight the contradiction in their reasoning and to defend His authority over evil spirits.
The passage implies the hypocrisy of the Pharisees, who criticized Jesus for associating with sinners and questioned His methods, yet could not deny His power and authority. Jesus's interactions with the Pharisees emphasized His larger mission of bringing spiritual healing and transformation rather than conforming to established religious norms.
