Matthew 16:2-4

New Matthew Bible

² He answered and said to them, At evening you say the weather will be fair, and that because the sky is red; ³ and in the morning you say it will be bad weather today, and that because the sky is cloudy and red. O ye hypocrites, you can discern the aspect of the sky, and can you not discern the signs of the times? ⁴ The froward and adulterous nation seeks a sign, but no other sign shall be given to them than the sign of the prophet Jonah.

So he left them, and departed.
