Matthew 16:1-8

1 Then some P'rushim and Tz'dukim came to trap Yeshua by asking him to show them a miraculous sign from Heaven.
2 But his response was, "When it is evening, you say, `Fair weather ahead,' because the sky is red;
3 and in the morning you say, `Storm today!' because the sky is red and overcast. You know how to read the appearance of the sky, but you can't read the signs of the times!
4 A wicked and adulterous generation is asking for a sign? It will certainly not be given a sign -- except the sign of Yonah!" With that he left them and went off.
5 The talmidim, in crossing to the other side of the lake, had forgotten to bring any bread.
6 So when Yeshua said to them, "Watch out! Guard yourselves against the hametz of the P'rushim and Tz'dukim,"
7 they thought he said it because they hadn't brought bread.
8 But Yeshua, aware of this, said, "Such little trust you have! Why are you talking with each other about not having bread?
