Menelaus (Hebrew: מנלאוס) was High Priest in Jerusalem from 171 BC to about 161 BC. He was the successor of Jason, the brother of Onias III.
The sources are divided as to his origin. According to II Maccabees, he belonged to the Tribe of Benjamin and was the brother of the Simeon who had denounced Onias III to Seleucus IV Philopator, and revealed to the Syrians the existence of the treasure of the Temple; according to Flavius Josephus, Menelaus was the brother of Onias III and Jason, his two predecessors as High Priest, and also bore the name Onias. It is possible that Josephus confused Simeon, the brother of Menelaus, with Simeon, the father of Onias and Jason.
Although during the three years of his pontificate Jason had given many proofs of his attachment to the Hellenistic party (by building a gymnasium in Jerusalem and by introducing many Greek customs) the zealous 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.
