Where then is my whale?

[asthenos]

The Pharisees also with the Sadducees came, and tempting desired him that he would show them a sign from heaven. He answered and said unto them, "When it is evening, ye say, 'It will be fair weather: for the sky is red.' And in the morning, 'It will be foul weather today: for the sky is red and lowering.' O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times? A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonah." And he left them, and departed.
