Matthew 23:13
But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people's faces. For you neither enter yourselves nor allow those who would enter to go in. The first woe: the scribes and Pharisees shut the kingdom. The door-shutting communicates the gatekeeping function that the Pharisees have assumed — and their failure in that function: they neither enter themselves nor allow those trying to enter to do so. The teachers who should be opening the kingdom are closing it.
