6 - rejection at Nazareth; 12 sent out; Herod haunted by reports of Jesus, remembering his execution of John; 5000 fed; Jesus walks on water and heals
7 - Pharisees object to eating without ritually cleansing. Jesus says external stuff like that doesn't make you unclean in God's sight, but the sin that comes out of you does. A gentile is healed, getting crumbs from the master's table.
8 - 4000 fed; disciples warned against Pharisees; Peter confesses Jesus is God's Christ; He predicts His death and resurrection, Peter opposes Him! Jesus calls us to sacrifice and denial in an adulterous world.
