Mark 8:11-18

11The Pharisees came and began to question Jesus. To test him, they asked him for a sign from heaven. 12He sighed deeply and said, “Why does this generation ask for a sign? Truly I tell you, no sign will be given to it.”

13Then he left them, got back into the boat and crossed to the other side.

The Yeast of the Pharisees and Herod 14The disciples had forgotten to bring bread, except for one loaf they had with them in the boat.

15“Be careful,” Jesus warned them. “Watch out for the yeast of the Pharisees and that of Herod.”

16They discussed this with one another and said, “It is because we have no bread.” 17Aware of their discussion, Jesus asked them: “Why are you talking about having no bread? Do you still not see or understand? Are your hearts hardened? 18Do you have eyes but fail to see, and ears but fail to hear? And don’t you remember?
