Matthew 23:25
Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and the plate, but inside they are full of greed and self-indulgence. The sixth woe: the clean outside and the unclean inside. The cup-and-plate image applies the ritual purity framework to the Pharisees themselves: the same concern for ritual cleanness that governs their vessel-washing does not govern their inner life. The greed and self-indulgence that fill the inside are the moral impurity that the external cleaning does not address.
