“When the Pharisees
That Jesus had silenced
They gathered together.”
Οἱ δὲ Φαρισαῖοι ἀκούσαντες ὅτι ἐφίμωσεν τοὺς Σαδδουκαίους, συνήχθησαν ἐπὶ τὸ αὐτό,
This comment is unique to Matthew, who did not like the Pharisees. Thus, when the Pharisees heard (Οἱ δὲ Φαρισαῖοι ἀκούσαντες) that Jesus had silenced or muzzled the Sadducees (ὅτι ἐφίμωσεν τοὺς Σαδδουκαίους), they gathered together to plan their next step against Jesus (συνήχθησαν ἐπὶ τὸ αὐτό).
