Specifically for the mitzvah of כבוד לחכמים, what is the punishment a person is given? I'm looking mainly for the divine punishment, but if human punishment applies I'd like that too.
Based on the story of "shviskel" near the beginning of the forth chapter of mesechet Kedushin we see that both excommunication (nidui) and flogging are appropriate punishments for disrespect to rabbis and their emissaries. This is by human hands. (although nidui might involve heavenly punishment)
