Matthew 16:1-4 - The Signs Of The Times
Luke 12:54-56
54 And he said to the crowds, "When you see a cloud rise in the west, you say at once, 'It is going to rain,' and it does. 55 And when you see the south wind blowing, you say, 'It is going to be very hot,' and it is. 56 You hypocrites! You know how to interpret the look of the earth and sky; and why can you not interpret this present time?
