Matthew 16:5-12 - Beware The Leaven Of The Pharisees And Sadducees
5 When the disciples went across the lake, they forgot to take any bread.
6 And Jesus said to them, "Look out, and be on your guard against the yeast of the Pharisees and Sadducees!"
7 But they were discussing something with one another, and saying, "We have not brought any bread!"
8 Jesus noticed it and said, "Why are you discussing with one another your being without bread? You have so little faith! 9 Do you not understand yet? Do you not remember the five loaves for the five thousand, and how many baskets full you gathered up? 10 Nor the seven loaves for the four thousand, and how many baskets full you gathered up? 11 Why do you not see that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees!" 12 Then they understood that he was warning them not against yeast but against the teaching of the Pharisees and Sadducees.
