1. Unbelief - The Pharisees did not accept Jesus as the Messiah.
2. Hypocrisy - The Pharisees appeared on the outside to be righteous but inwardly they were evil.
3. Temporal Values - The Pharisees were interested in present power and reward by pleasing men rather than eternal reward that comes from pleasing God.
Walk with the Lord and beware of "leaven"!!!
