Why was all Jerusalem troubled along with King Herod?

All Jerusalem was troubled along with King Herod because the arrival of the Magi, who sought the newborn "King of the Jews," posed a threat to Herod's authority. The announcement of a new king stirred anxiety among the Jewish populace and the ruling elite, as it hinted at potential upheaval and challenges to Herod's reign. This fear of disruption and the implications of a rival king created widespread unrest in the city.
