Woe to you, teachers of the law and Pharisees, you hypocrites! You clean the outside of the cup and dish, but inside they are full of greed and self-indulgence. Blind Pharisee! First clean the inside of the cup and dish, and then the outside also will be clean.
My wife's insight is kind of obvious when you think of it, but it had never occurred to me. It's this: Jesus -- through whom everything was made, the one who holds the entire universe together -- washed dishes. At some point in his life, he had to clean dinnerware. That is how far down the food chain he was willing to go in order to show us how much he loves us. Pretty amazing.
