Matthew 12:25
Knowing their thoughts, he said to them: every kingdom divided against itself is laid waste, and no city or house divided against itself will stand. Jesus knows the Pharisees' thoughts — a recurring feature of Matthew's presentation — and addresses the logical incoherence of the Beelzebul charge directly. The divided-house argument is simple: a kingdom, city, or house divided against itself cannot stand. If Satan is casting out Satan, Satan is destroying his own operation.
