1 And Pharisees and Sadducees approached him to test him, and they asked him to show them a sign from heaven.
2 But he responded by saying to them: "When evening arrives, you say, 'It will be calm, for the sky is red,'
3 and in the morning, 'Today there will be a storm, for the sky is red and gloomy.' So then, you know how to judge the appearance of the sky, but you are unable to know the signs of the times?
4 An evil and adulterous generation seeks a sign. And a sign shall not be given to it, except the sign of the prophet Jonah." And leaving them behind, he went away.
