And there came to him the Pharisees and Sadducees tempting: and they asked him to shew them a sign from heaven.

2 But he answered and said to them: When it is evening, you say, It will be fair weather, for the sky is red.

3 And in the morning: To day there will be a storm, for the sky is red and lowering. You know then how to discern the face of the sky: and can you not know the signs of the times?

4 A wicked and adulterous generation seeketh after a sign: and a sign shall not be given it, but the sign of Jonas the prophet. And he left them, and went away.

5 And when his disciples were come over the water, they had forgotten to take bread.

6 Who said to them: Take heed and beware of the leaven of the Pharisees and Sadducees.

7 But they thought within themselves, saying: Because we have taken no bread.

8 And Jesus knowing it, said: Why do you think within yourselves, O ye of little faith, for that you have no bread?

9 Do you not yet understand, neither do you remember the five loaves among five thousand men, and how many baskets you took up?

10 Nor the seven loaves, among four thousand men, and how many baskets you took up?

11 Why do you not understand that it was not concerning bread I said to you: Beware of the leaven of the Pharisees and Sadducees?

12 Then they understood that he said not that they should beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.
