Luke 12:1-3 - Warning Against Hypocrisy
1 Meanwhile as the people gathered in thousands, until they actually trod on one another, he proceeded to say to his disciples first of all, "Beware of the yeast of the Pharisees, that is, hypocrisy. 2 There is nothing covered up that is not going to be uncovered, nor secret that is not going to be known. 3 For what you say in the darkness will be heard in the light, and what you whisper in someone's ear, behind closed doors, will be proclaimed from the housetops.
