Matthew 16:2
He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red.
He answered and said unto them,.... Knowing full well their views, and having wrought sufficient miracles to confirm his Messiahship, he thought fit to give them no other answer than this:
When it is evening, ye say, It will be fair weather, for the sky is red; when the sun is setting, it is a common thing for you to say, looking up to the heavens, and observing the face and colour of them, that it is like to be fair weather; no rain, that night, nor perhaps the next day, for the sky is red like fire, through the rays of the sun; which show the clouds to be very thin, and so will soon waste away, and consequently fine weather must follow.
