Matthew 23:27; Matthew 23:28

27 “Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean.

28 In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness.
