17 After Jesus and his disciples had left the crowd and gone into the house, they asked him what these sayings meant.
18 He answered, “Don't you know what I am talking about by now? You surely know that the food you put into your mouth cannot make you unclean.
19 It doesn't go into your heart, but into your stomach, and then out of your body.” By saying this, Jesus meant that all foods were fit to eat.
20 Then Jesus said:What comes from your heart is what makes you unclean.
21 Out of your heart come evil thoughts, vulgar deeds, stealing, murder,
22 unfaithfulness in marriage, greed, meanness, deceit, indecency, envy, insults, pride, and foolishness.
23 All of these come from your heart, and they are what make you unfit to worship God.
