Matthew 15:20
These are what defile a person. But to eat with unwashed hands does not defile anyone. The conclusion: the catalog of heart-sourced sins is what defiles; eating with unwashed hands does not. The Pharisees' concern about handwashing addressed the wrong category of defilement. The washing that matters is the washing of the heart — the circumcision of the heart that Deuteronomy 30:6 promised and Jeremiah 31:33 elaborated.
