1 Now when the Pharisees and Sadducees came to test Jesus, they asked him to show them a sign from heaven.2 He said, "When evening comes you say, 'It will be fair weather, because the sky is red,'3 and in the morning, 'It will be stormy today, because the sky is red and darkening.' You know how to judge correctly the appearance of the sky, but you cannot evaluate the signs of the times.4 A wicked and adulterous generation asks for a sign, but no sign will be given to it except the sign of Jonah." Then he left them and went away.
- The Pharisees and Sadducees, usually opponents, unite here to test Jesus, revealing their shared hostility towards him.
- Their request for a "sign from heaven" implies a demand for an undeniable, spectacular miracle directly attributable to God, likely beyond the healings and exorcisms Jesus already performed.
- Jesus rebukes their hypocrisy: they can interpret natural weather patterns but fail to recognize the significance of his ministry and the fulfillment of prophecy happening before them ("the signs of the times").
- Jesus calls the generation "wicked and adulterous," echoing Old Testament prophets who used "adultery" to describe spiritual unfaithfulness and idolatry (e.g., Hosea 2:2-5).
- The "sign of Jonah" primarily refers to Jesus' coming death, burial (three days, like Jonah in the fish), and resurrection (Matthew 12:39-40). It might also allude to the call for repentance preached by Jonah, which the Ninevites heeded, unlike this generation.
- Jesus refuses to perform a sign on demand for skeptics seeking to trap him, contrasting with signs performed out of compassion or to build genuine faith.
- His abrupt departure emphasizes his rejection of their faithless demand.
