Matthew 16:1–12

¹Then the Pharisees and Sadducees came and tested Jesus by asking Him to show them a sign from heaven.

²But He replied, “When evening comes, you say, ‘The weather will be fair, for the sky is red,’ ³and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but not the signs of the times.^{a 4}A wicked and adulterous generation demands a sign, but none will be given it except the sign of Jonah.” Then He left them and went away.

⁵When they crossed to the other side, the disciples forgot to take bread. ⁶“Watch out!” Jesus told them. “Beware of the leaven of the Pharisees and Sadducees.”

⁷They discussed this among themselves and concluded, “It is because we did not bring any bread.”

⁸Aware of their conversation, Jesus said, “You of little faith, why are you debating among yourselves about having no bread? ⁹Do you still not understand? Do you not remember the five loaves for the five thousand, and how many basketfuls you gathered? ¹⁰Or the seven loaves for the four thousand, and how many basketfuls you gathered? ¹¹How do you not understand that I was not telling you about bread? But beware of the leaven of the Pharisees and Sadducees.”

¹²Then they understood that He was not telling them to beware of the leaven used in bread, but of the teaching of the Pharisees and Sadducees.
