Shortly after healing a leper and driving out a bunch of demons, Jesus returns home to Capernaum. (When did he move from Nazareth?) Crowds prevent a group of guys from getting their paralyzed bud close to him, so they come in through the roof.
Then Jesus whips out the big whammy - he doesn't just heal the guy, but makes a statement that borders strongly on blasphemy. People seem to be more amazed at the healing, though. Shortly thereafter, Levi takes early retirement from the RRS to join him.
In verses 21-22 (the "old wineskins" passage) Jesus seems to say that his ministry is a radical break from traditional Judaism. And on a Sabbath shortly thereafter, he allows his followers to gather grain in defiance of the legalists. (For the farmer's sake, one hopes it was just Jesus and the five disciples, rather than the hordes of followers.)
I'm curious if the disciples were ignorant of the strict interpretation of the law that forbade harvesting on the Sabbath - even plucking grains to eat out of hand - or if they had asked Jesus whether they could do so.
