And he healed many that were sick of various diseases, and cast out many demons; and allowed not the demons to speak, because they knew him.

Theophylact of Ochrid
AD 1107
Because the multitude thought that it was not lawful to heal on the sabbath day, they waited for the evening, to bring those who were to be healed to Jesus. Wherefore it is said, “And at even, when the sun had set. "There follows, “and He healed many that were vexed with divers diseases.”.
Or he says, “many”, because there were some faithless persons, who could not at all be cured on account of their unfaithfulness. Therefore He healed many of those who were brought, that is, all who had faith. It goes on, “and cast out many devils.”.
Furthermore, the reason that He forbade the devils to speak, was to teach us not to believe them, even if they say true. For if once they find persons to believe them, they mingle truth with falsehood.
