NIV Matthew 16:1-3
1. The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven.
2. He replied, "When evening comes, you say, `It will be fair weather, for the sky is red,'
3. and in the morning, `Today it will be stormy, for the sky is red and overcast.' You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.
NIV Luke 12:54-56
54. He said to the crowd: "When you see a cloud rising in the west, immediately you say, `It's going to rain,' and it does.
55. And when the south wind blows, you say, `It's going to be hot,' and it is.
56. Hypocrites! You know how to interpret the appearance of the earth and the sky. How is it that you don't know how to interpret this present time?
