The meal in the house of one of the Pharisees, because of its rich symbolic meaning--a feast as the Messianic Kingdom--immediately gives Jesus material for new parables about the Kingdom He came to proclaim to people.
Fish, as the saying goes, look for deeper water, and people look for a better place. None of the invited guests wants to sit with a man disfigured by dropsy; let him come another day, since seeking healing on the Sabbath is a sin. Feasting is best with friends and neighbors whom you know, who smell pleasant, and who will not let your rich dishes disappear without return; they too will invite you to a "return dinner." And if you are a guest, it would also be good to sit at the head of the table, closer to the generous host.
This is ordinary human life, but for every situation Jesus finds the apt word, without moralizing or angry denunciations. He simply, as if joking, shows us, sitting with Him at table in the Pharisee's house, the whole absurdity of our normal life when one looks at it "from the point of view" of God's Kingdom.
