The Leaven of the Pharisees and the Sadducees

16 The Pharisees and Sadducees approached,^(A) and tested him, asking him to show them a sign from heaven.^{(B) 2} He replied, “When evening comes you say, ‘It will be good weather because the sky is red.’ ³ And in the morning, ‘Today will be stormy because the sky is red and threatening.’ You^[a] know how to read the appearance of the sky, but you can’t read the signs of the times.^{[b] 4} An evil and adulterous generation demands a sign, but no sign will be given to it except the sign of^[c] Jonah.”^(C) Then he left them and went away.
