John Chrysostom — as excerpted in the Catena Aurea on Matthew 9:1-8

“The Scribes in their desire to spread an ill report of Him, against their will made that which was done be more widely known; Christ using their envy to make known the miracle. For this is of His surpassing wisdom to manifest His deeds through His enemies; whence it follows, Behold, some of the Scribes said among themselves, This man blasphemeth.”
