“Jesus answered them.
‘When it is evening,
You say.
‘It will be fair weather
Because the sky is red.’
In the morning,
You say.
‘It will be stormy today
Because the sky is red
And threatening.’
You know how to interpret
The appearance of the sky.
But you cannot interpret
The signs of the times.”
ὁ δὲ ἀποκριθεὶς εἶπεν αὐτοῖς Ὀψίας γενομένης λέγετε Εὐδία, πυρράζει γὰρ ὁ οὐρανός·
καὶ πρωΐ Σήμερον χειμών, πυρράζει γὰρ στυγνάζων ὁ οὐρανός. τὸ μὲν πρόσωπον τοῦ οὐρανοῦ γινώσκετε διακρίνειν, τὰ δὲ σημεῖα τῶν καιρῶν οὐ δύνασθε;
Matthew is the only one who has this weather saying of Jesus, although Luke, chapter 12:54-56, has Jesus issue some weather commentary about northern and southern winds and rain. Jesus told the Pharisees and Sadducees that they could read the signs in the sky about weather and storms, but they were unable to recognize the signs in their own world. Most farmers are aware of the red sky in the morning was a warning, while the red sky at night was a delight. Jesus answered them (ὁ δὲ ἀποκριθεὶς εἶπεν αὐτοῖς) that at evening time, people would say that there would be good or fair weather if the setting sun in the sky was red (Ὀψίας γενομένης λέγετε Εὐδία, πυρράζει γὰρ ὁ οὐρανός). On the other hand, if the sky was red today in the morning, they thought that it would be a stormy day (καὶ πρωΐ Σήμερον χειμών, πυρράζει γὰρ στυγνάζων ὁ οὐρανός). Then he asked them how come they were so good at discerning the overcast stormy weather signs in the heavens (τὸ μὲν πρόσωπον τοῦ οὐρανοῦ γινώσκετε διακρίνειν), but they were unable to interpret the signs of the times (τὰ δὲ σημεῖα τῶν καιρῶν οὐ δύνασθε), since the weather signs were in the heavenly skies.
