"The scribes and the Pharisees have taken their seat on the chair of Moses.
Therefore, do and observe all things whatsoever they tell you, but do not follow their example.
For they preach but they do not practice.
They tie up heavy burdens hard to carry and lay them on people's shoulders, but they will not lift a finger to move them.
All their works are performed to be seen. MT 23:1-12
Know anybody like this?
