WPNT(i)
1 The Pharisees and Sadducees came, and testing Him they asked Him to show them a sign from heaven.
2 But in answer He said to them: “When it is evening you say, ‘Fair weather, for the sky is red’;
3 and in the morning, ‘Today will be stormy, for the sky is red and overcast’. Hypocrites! You know how to discern the face of the sky but cannot discern the signs of the times.
