Luke 11:52

“Woe to you lawyers! for you took away the key of knowledge. You did not enter in yourselves, and those who were entering in you hindered.”

The final charge against the Doctors of the Law is that they kept from the people the knowledge of how they could enter the Kingly Rule of God, or the knowledge of the Scriptures. They took away ‘the key of knowledge' which opened the way to these things. By keeping people's minds filled with trivialities and with various requirements, and making parts of the Scriptures into nothing better than riddles they effectively silenced the voice of God. They did not want to use the key to enter in themselves, and by their methods they put obstacles in the way of any who would enter in. Thus they were worthy of condemnation.
