Mk 8:14-17

The Leaven of the Pharisees. 14^d They had forgotten to bring bread, and they had only one loaf with them in the boat. 15^* He enjoined them, “Watch out, guard against the leaven of the Pharisees and the leaven of Herod.” 16They concluded among themselves that it was because they had no bread. 17When he became aware of this he said to them, “Why do you conclude that it is because you have no bread? Do you not yet understand or comprehend? Are your hearts hardened?^e
