Luke 12:54-56

⁵⁴And he said also to the crowds, When ye see a cloud rising out of the west, straightway ye say, A shower is coming; and so it happens.

⁵⁵And when ye see the south wind blow, ye say, There will be heat; and it happens.

⁵⁶Hypocrites, ye know how to judge of the appearance of the earth and of the heaven; how is it then that ye do not discern this time?
