So pay attention to what is inside.

A Pharisee asked Jesus to eat with him

The Pharisee was surprised when he saw that Jesus did not wash his hands first before the meal. 

The Lord said to him, “The washing you Pharisees do is like cleaning only the outside of a cup or a dish. But what is inside you? You want only to cheat and hurt people. The same one who made what is outside also made what is inside. So pay attention to what is inside. Then you will be fully clean.”
