suffereth violence
It has been much disputed whether the "violence" here is external, as against the kingdom in the persons of John the Baptist and Jesus; or that, considering the opposition of the scribes and Pharisees, only the violently resolute would press into it. Both things are true. The King and His herald suffered violence, and this is the primary and greater meaning, but also, some were resolutely becoming disciples.
