Prior to the rise of the sun of righteousness, the plant that provided shade was flourishing, and Israel thrived; but once the sun rose, it illuminated, dispersing the darkness over Nineveh.
The psalm, referencing this event, states: "at the appearance of the dawn," and it is further noted, "I am a worm, and not a man." This illustrates that the gourd, deprived of divine assistance, lost all its verdant beauty. The Lord directed the heat and burning wind, as foretold by the prophet Hosea: "The Lord shall bring a hot wind from the wilderness upon them, drying up their veins and emptying their springs." Consequently, Jonah grew weary and once again longed to die in the waters of baptism alongside Israel, hoping to regain the vitality he had forfeited through his refusal. Hence, Peter addressed the parched members of Israel, saying, "Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of your sins, and you shall receive the gift of the Holy Spirit." Some interpret the worm and the burning wind as symbols of the Roman generals who, following the resurrection of Christ, completely ravaged Israel.
