Matthew 12:35
The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil. The principle of the heart's treasure applies to the contrast between Jesus (who brings forth good from his good treasure) and the Pharisees (who bring forth evil from their evil treasure). The Beelzebul charge is an example of evil treasure producing evil speech. The good works of Jesus are the evidence of good treasure.
