Luke 12:1-2

1In the meantime, after so many thousands of the people had gathered that they were stepping on one another, Jesus began speaking first of all to His disciples, “Be continually on your guard against the leaven of the Pharisees [that is, their pervasive, corrupting influence and teaching], which is hypocrisy [producing self-righteousness].

2But there is nothing [so carefully] concealed that it will not be revealed, nor so hidden that it will not be made known.
