“But the Pharisees said.

‘He casts out demons

By the leader of demons.’”

οἱ δὲ Φαρισαῖοι ἔλεγον Ἐν τῷ ἄρχοντι τῶν δαιμονίων ἐκβάλλει τὰ δαιμόνια.

There is something similar to this in chapter 12:24 of Matthew and Luke, chapter ll:15.  The Pharisees complained (οἱ δὲ Φαρισαῖοι ἔλεγον) that Jesus was casting out demons or evil spirits (ἐκβάλλει τὰ δαιμόνια) because he was the leader or the prince of these demons or evil spirits (Ἐν τῷ ἄρχοντι τῶν δαιμονίων).  These Pharisees did not say that Jesus did’t have power over these evil spirits.  Quite the opposite, they said that he got his power from evil spirits or demons themselves because he was their leader.  The Pharisees were a political party, a social movement, and a religious school of thought that became the basis for later Rabbinic Judaism.  They had they own expert explanations of Jewish law that sometimes appeared to be hypocritical or arrogant, with the letter of the law above its spirit.  They had a form of Judaism that extended beyond the Temple.  The Pharisees in the New Testament, engaged in conflicts with Jesus and his disciples, as here.  However, Paul the Apostle may have been a Pharisee before his conversion.  Maybe Jesus and some of his followers were Pharisees, so that these arguments with the Pharisees may have been internal arguments.  Or is this portrait of the Pharisees in the New Testament a caricature, since the late first century Christians were fighting with the emerging Rabbinic Pharisees?
