Luke 12:54-56

54 Then He also said to the multitudes, "Whenever you see a cloud rising out of the west, immediately you say, 'A shower is coming'; and so it is.

55 And when you see the south wind blow, you say, 'There will be hot weather'; and there is.

56 Hypocrites! You can discern the face of the sky and of the earth, but how is it you do not discern this time?
