Matthew 16:3-13

3 And in the morning, [It will be] foul weather to-day: for the sky is red and lowering. O [ye] hypocrites, ye can discern the face of the sky; but can ye not [discern] the signs of the times?

4 A wicked and adulterous generation seeketh for a sign; and there shall no sign been to it, but the sign of the prophet Jonah. And he left them, and departed.

5 And when his disciples had come to the other side, they had forgotten to take bread.

6 Then Jesus said to them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.

7 And they reasoned among themselves, saying, [It is] because we have taken no bread.

8 [Which] when Jesus perceived, he said to them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread?

10 Neither the seven loaves of the four thousand, and how many baskets ye took up?

11 How is it that ye do not understand that I spoke not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?

12 Then they understood that he did not caution them against the leaven of bread, but against the doctrine of the Pharisees and of the Sadducees.

13 When Jesus came into the borders of Cesarea Phillippi, he asked his disciples, saying, Who do men say that I the Son of man am?
