RKJNT(i)
1 The Pharisees and the 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 you hypocrites, you can discern the face of the sky; but can you not discern the signs of the times?
