The passage describes a dispute between Jesus and some Pharisees and scribes over Jewish dietary laws and traditions. The Pharisees criticize Jesus' disciples for eating with unwashed hands, which violates the tradition of the elders. Jesus accuses the Pharisees of elevating human traditions over God's commandments, citing an example of how they allow people to avoid supporting their parents by declaring gifts to God. Jesus then tells the crowd that what goes into a person cannot defile them, but rather what comes out of their heart, like evil intentions, are what truly defile a person.
