"Then the Pharisees and Sadducees came, and testing Him asked that He would show them a sign from heaven.
2 He answered and said to them, “When it is evening you say, ‘It will be fair weather, for the sky is red’;
3 and in the morning, ‘It will be foul weather today, for the sky is red and threatening.’ O ye Hypocrites! You know how to discern the face of the sky, but you cannot discern the signs of the times.
4 A wicked and adulterous generation seeks after a sign, and no sign shall be given to it except the sign of the prophet Jonah.” And He left them and departed."
