Matthew 16:1–12

¹And the Pharisees and Sadducees came, and to test him they asked him to show them a sign from heaven. ²He answered them,^r “When it is evening, you say, ‘It will be fair weather; for the sky is red.’ ³And in the morning, ‘It will be stormy today, for the sky is red and threatening.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times. ⁴An evil and adulterous generation seeks for a sign, but no sign shall be given to it except the sign of Jonah.” So he left them and departed.

⁵When the disciples reached the other side, they had forgotten to bring any bread. ⁶Jesus said to them, “Take heed and beware of the leaven of the Pharisees and Sadducees.” ⁷And they discussed it among themselves, saying, “We brought no bread.” ⁸But Jesus, aware of this, said, “O men of little faith, why do you discuss among yourselves the fact that you have no bread? ⁹Do you not yet perceive? Do you not remember the five loaves of the five thousand, and how many baskets you gathered? ¹⁰Or the seven loaves of the four thousand, and how many baskets you gathered? ¹¹How is it that you fail to perceive that I did not speak about bread? Beware of the leaven of the Pharisees and Sadducees.” ¹²Then they understood that he did not tell them to beware of the leaven of bread, but of the teaching of the Pharisees and Sadducees.
