Onias I

Onias I (Hebrew: חוניו ; Honiyya or Honio ben Jaddua) was the son of the Jaddua mentioned in Nehemiah. According to Josephus, this Jaddua is said to have been a contemporary of Alexander the Great. I Maccabees regards Onias as a contemporary of the Spartan king Areus I (309-265 BCE).

Simon the Just extolled in the Wisdom of Sirach (according to the Hebrew text the son of Jonathan, but according to the Greek text the son of Onias) and in legend was probably the son of Onias I or, according to some, of the latter's grandson Onias II.
