Then the disciples understood that Jesus wasn’t telling them to watch out for the yeast that’s used in bread. He was warning them against the teaching of the Pharisees and Sadducees.
I tell you, unless your righteousness is even better than the righteousness of the Pharisees and the teachers of the law, you won’t enter the kingdom of heaven.
But when he saw many Pharisees and Sadducees coming to be baptized, John said to them, “You little snakes! Who warned you to try to escape the punishment that’s coming?
How can you possibly not understand? I wasn’t talking to you about bread. I was telling you to watch out for the yeast of the Pharisees and Sadducees.”
