1 And the Pharisees and Sadducees came, and trying him asked him to show them a sign from heaven.
2 But he answered and said unto them, When it is evening, ye say, It will be fair weather: for the heaven is red.
3 And in the morning, It will be foul weather to-day: for the heaven is red and lowering. Ye know how to discern the face of the heaven; but ye cannot discern the signs of the times.
4 An evil and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of Jonah. And he left them, and departed. Mt 16

20 And he said, I will hide my face from them, I will see what their end shall be: For they are a very perverse generation, Children in whom is no faithfulness. Dt 32
