1 The Pharisees also, with the Sadducees, came, and tempting Jesus, desired him that he would show them a sign from heaven.

2 And he answered and said unto them, When it is evening ye say, The weather is fair, for the sky is red; and in the morning ye say, The weather is foul today; for the sky is red and lowering.

3 O hypocrites! ye can discern the face of the sky; but ye cannot tell the signs of the times.

4 A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the Prophet Jonas.

5 And he left them and departed.

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

7 Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.

8 And they reasoned among themselves, saying, He said this because we have taken no bread.

9 And when they reasoned among themselves, Jesus perceived it; and he said unto them, O ye of little faith! why reason ye among yourselves, because ye have brought no bread?

10 Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up?

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

12 How is it that ye do not understand, that I spake not unto you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?

13 Then understand they, how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
