Mark 8:15-16

¹⁵As they were going, Jesus warned them against the attitudes the Pharisees and Herod Antipas had, attitudes that were having a bad effect on other people. He did this by telling them a parable. He said, “Be careful! Beware of the yeast of the Pharisees and the yeast of Herod!”

¹⁶The disciples misunderstood him. So they said to one another, “ He must have said that because we have no bread.”
