Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the dish, but inside they are full of robbery and self-indulgence. You blind Pharisee, first clean the inside of the cup and of the dish, so that the outside of it may become clean also.
It doesn’t matter how clean the outside of the cup is…
if the inside is dirty, then no matter how clean the water is that you put in the cup, the water will come out of the cup dirty.
