Onias III

Onias III, son of Simon II (Hebrew: חוֹנִיּוֹ, romanized: Ḥoniyyo) called Onias Simonides in Koine Greek, was High Priest of Israel during the Second Temple period under the rule of the Seleucid Empire. He is described in the scriptures as a pious man who opposed the Hellenization of Judea.

Onias was usurped by his brother Jason after the ascension of Antiochus IV Epiphanes as ruler of the Seleucid Empire in 175 BCE.
