Daniel 11:20

Antiochus’ elder son, Seleucus IV, succeeded his father. He taxed his people, including the Jews, so heavily to pay Rome that his Jewish tax collector, Heliodorus (2 Maccabees 3:7), poisoned him. Heliodorus was evidently the oppressor that Seleucus sent through "the jewel of his kingdom," namely, Israel, collecting taxes. This assassination set the stage for the terrible persecutions of the Jews that followed. Thus Seleucus IV did not die because of mob violence, as his father had, or in battle, but from poison, as this verse predicted.
