Matthew 16:2-3

He answered them
Some manuscripts omit the following words to the end of verse 3
b “When it is evening, you say, ‘It will be fair weather, for the sky is red.’
And in the morning, ‘It will be stormy today, for the sky is red and threatening.’ c You know how to interpret the appearance of the sky, but you cannot interpret d the signs of the times.
