Luke 12:54-57

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?

57And why even of yourselves judge ye not what is right?
