As thousands of people crowded together, so that they were stepping on each other, Jesus said first to his disciples, “Be on guard against the yeast of the Pharisees—I mean their hypocrisy.
And he went on to say to them all, “Watch out and guard yourselves from every kind of greed; because your true life is not made up of the things you own, no matter how rich you may be.”
