Bible: Matthew 16:1-12
The Demand for a Sign
16:1 Now when the Pharisees 1 and Sadducees 2 came to test Jesus, 3 they asked him to show them a sign from heaven. 4 16:2 He 5 said, “When evening comes you say, ‘It will be fair weather, because the sky is red,’ 16:3 and in the morning, ‘It will be stormy today, because the sky is red and darkening.’ 6 You know how to judge correctly the appearance of the sky, 7 but you cannot evaluate the signs of the times. 16:4 A wicked and adulterous generation asks for a sign, but no sign will be given to it except the sign of Jonah.” Then 8 he left them and went away.
The Yeast of the Pharisees and Sadducees
16:5 When the disciples went to the other side, they forgot to take bread. 16:6 “Watch out,” Jesus said to them, “beware of the yeast of the Pharisees 9 and Sadducees.” 10 16:7 So 11 they began to discuss this among themselves, saying, “It is because we brought no bread.” 16:8 When Jesus learned of this, 12 he said, “You who have such little faith! 13 Why are you arguing 14 among yourselves about having no bread? 16:9 Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many baskets you took up? 16:10 Or the seven loaves for the four thousand and how many baskets you took up? 16:11 How could you not understand that I was not speaking to you about bread? But beware of the yeast of the Pharisees and Sadducees!” 16:12 Then they understood that he had not told them to be on guard against the yeast in bread, but against the teaching of the Pharisees and Sadducees.
