Matthew 16:2 KJV
He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red.
Matthew 16:2, King James Version
In context
1 The Pharisees also with the Sadducees came, and tempting desired him that he would shew them a sign from heaven.
2 He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red.
3 And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times?
