Matthew 23:2-4

2He said, ‘The teachers of God's Law and the Pharisees have authority to explain the Law of Moses.

3So you must obey everything that they teach you. But you should not do the same things that they do. They tell you what the Law of Moses teaches. But then they themselves do not obey it.

4The rules that they give you are difficult to obey. Their rules are like heavy luggage, which they make you carry. But they themselves will not help you to carry that luggage. They will not agree to use even one finger to help you.
