Matthew 16:1-9

1Now when the Pharisees and Sadducees came to test Jesus, they asked him to show them a sign from heaven.

2He said, “When evening comes you say, ‘It will be fair weather, because the sky is red,’

3and in the morning, ‘It will be stormy today, because the sky is red and darkening.’ You know how to judge correctly the appearance of the sky, but you cannot evaluate the signs of the times.

4A wicked and adulterous generation asks for a sign, but no sign will be given to it except the sign of Jonah.” Then he left them and went away.

5When the disciples went to the other side, they forgot to take bread.

6“Watch out,” Jesus said to them, “beware of the yeast of the Pharisees and Sadducees.”

7So they began to discuss this among themselves, saying, “It is because we brought no bread.”

8When Jesus learned of this, he said, “You who have such little faith! Why are you arguing among yourselves about having no bread?

9Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many baskets you took up?
