The Seleucid Empire controlled Jerusalem during Onias' tenure and Seleucus IV Philopator was friendly to the Jews and defrayed all expenses connected with their sanctuary. According to 2 Maccabees, a Hellenizing official of the Temple, Simon, a member of the Tribe of Benjamin, induced Seleucus through his official Heliodorus to plunder the Temple. The attempt was unsuccessful and the court never forgave the High Priest. When Antiochus IV Epiphanes became king in 175 BCE, Onias was obliged to yield to his own brother, Jason, a Hellenizer. According to Josephus, Jason became high priestafter the death of Onias, the latter's son being then a minor. Josephus strangely identifies the high priest who succeeded Jason as the brother of Onias and Jason, likewise was called Onias, asserting that he did not assume the name of Menelaus until later; for according to this statement there must have been two brothers of the same name. While this confusion may be due to the Greek transcription of the related Hebrew names Johanan, Honiyya, and Nehonya, the account of Josephus appears wholly unreliable for this very reason. According to II Macc. iv. 26, Menelaus was not an Aaronite, but brother of Simon and thus also a Benjaminite. When Menelaus removed some vessels from the Temple to curry favor with the Syrian nobles of the Seleucid Empire, Onias accused him publicly and then fled to the asylum of Daphne, near Antioch, where Menelaus, aided by the royal governor Andronicus, had him secretly assassinated, in defiance of justice and of his oath. The murdered priest was deeply mourned by both Jews and Greeks, and the king also, on his return, wept for him and sentenced Andronicus to death. Wellhausen and Willrich regard the story of the murder of Onias, as well as the entire list of high priests from Jaddua to the Maccabees, as legendary, while Emil Schürer and Benedikt Niese consider them historical. The passages in Daniel 8:10-11, 9:26 and 11:22 are generally referred to the murder of Onias. Onias III is the central figure of the legendary history of later times; the ByzantineChronicon Paschale says he officiated for twenty-four years, thus placing the beginning of his term of office under Egyptian rule. The Byzantine Chronographeion Syntomon follows Josephus in mentioning "another Onias" as the successor of Onias III., referring probably to Menelaus.
