Commentaries:
Instead of rejoicing and enjoying the mercy of God, Jonah wanted to see the people of Nineveh pay for their sins! It is clear by what Jonah says that he understood what God was doing. He understood God's mercy and forgiveness. He had a good understanding of God's character and His will, but from his own words in verse 2, he did not want God's mercy and grace to be showered on the people of Nineveh! They were Israel's enemies, and he did not want to have anything to do with bringing them good things from God. These pagan Assyrians were more receptive to God's will than Jonah was.
