WNT(i)
2 He replied, "In the evening you say, 'It will be fine weather, for the sky is red;'
3 and in the morning, 'It will be rough weather to-day, for the sky is red and murky.' You learn how to distinguish the aspect of the heavens, but the signs of the times you cannot.
4 A wicked and faithless generation are eager for a sign; but none shall be given to them except the sign of Jonah." and He left them and went away.
