Although during the three years of his pontificate Jason had given many proofs of his attachment to the Hellenistic party the Hellenists of the stamp of the Tobiads plotted his overthrow, suspecting him of partiality to traditional Judaism. At their head stood Menelaus. Having been sent to Antiochus to pay the annual tribute, he took the opportunity to outbid Jason and secure for himself the office of high priest. An officer named Sostrates was sent by Antiochus with a troop of Cyprian soldiers to subdue any opposition that might be attempted by the followers of the deposed high priest Jason and to collect at the same time the sum Menelaus had promised. Menelaus' first act was to seize the sacred vessels in the Temple stores in order to meet the obligations he had incurred. This act came to the ears of the deposed high priest Onias III, who publicly accused Menelaus of robbing the Temple. The latter, afraid of the consequences of this accusation, induced the king's lieutenant Andronicus, who had had his share of the plunder, to get rid of Onias before a formal complaint had been lodged with the king. Accordingly, Onias was decoyed from the sanctuary at Daphne, in which he had sought refuge, and murdered. Menelaus continued to plunder the treasures of the Temple until violence ensued, in which his brother Lysimachus met his death. He then brought before the king an accusation against the people of Jerusalem, that they were partisans of the Egyptians and persecuted him only because he was opposed to their party intrigues. This accusation caused the execution of several Jews who, although they proved beyond any doubt that Menelaus and Lysimachus had desecrated the Temple, were sentenced to death.
Conflict with Jason
Meanwhile, Jason had not abandoned his claims to the high-priesthood, and while Antiochus was waging war against Egypt he succeeded in making himself master of Jerusalem and in forcing Menelaus to seek refuge in the citadel. Antiochus regarded this proceeding as an affront upon his majesty, and, having been compelled by the Romans to leave Egypt, he marched against Jerusalem, massacred the inhabitants, and plundered the Temple; in this he is said to have been assisted by Menelaus. According to II Maccabees, it was Menelaus who persuaded Antiochus to Hellenize the Jewish worship, and thereby brought about the uprising of the Judeans under the guidance of the Maccabees. During the first years of the restoration of the Jewish worship Menelaus still remained high priest. He is said to have been put to death by Antiochus V Eupator when the latter made definite concessions to the Jews, the reason assigned being that Menelaus, by his counsel, was indirectly responsible for the Jewish rebellion.
