Luke 11:24
Be on your guard against the yeast of the Pharisees, which is hypocrisy — the Pharisees' danger to the disciples is not their power but their corruption, the hypocrisy that presents external piety as a substitute for heart transformation. What is covered will be uncovered and what is hidden will be known: there is nothing permanently concealed, and the Pharisees' hidden condition will be disclosed in the final judgment just as the disciples' private discipleship will be acknowledged before the angels of God.
