What action does Jonah take in response to the people's repentance?

In the biblical story of Jonah, when the people of Nineveh repent after hearing Jonah's message of impending judgment, Jonah's reaction is one of anger. This is significant because it highlights his internal struggle and the theme of God's mercy versus human feelings of fairness and justice. Instead of rejoicing over the Ninevites' change of heart and their decision to turn from their wicked ways, Jonah becomes upset because he feels that they do not deserve God's compassion and forgiveness.

This response emphasizes the complexity of Jonah's character and the broader message of the narrative regarding the nature of God's grace. Jonah had initially fled from God's call because he anticipated that should the people repent, God would show them mercy. This leads to a moment of deep personal conflict for Jonah, illustrating that even a prophet can struggle with understanding God's plans and the depth of divine mercy.
