1 And when the Pharisees and Sadducees came to test him, they asked him to show them a sign from heaven.
2 So he answered and said to them, “When evening comes you say, ‘It will be fair weather because the sky is red,’
3 and early in the morning, ‘Today it will be stormy weather, because the sky is red and darkening.’ You know how to evaluate correctly the appearance of the sky, but you are not able to evaluate the signs of the times.
4 An evil and adulterous generation seeks for a sign, and a sign will not be given to it except the sign of Jonah!” And he left them and went away.
