text: The Essenes (; Hebrew: , Isiyim; Greek: Ἐσσηνοί, Ἐσσαῖοι, or Ὀσσαῖοι, Essenoi, Essaioi, Ossaioi) or Essenians were a mystic Jewish sect during the Second Temple period that flourished from the 2nd century BCE to the 1st century CE.
  The Essene movement likely originated as a distinct group among Jews during Jonathan Apphus' time, driven by disputes over Jewish law and the belief that Jonathan's high priesthood was illegitimate. Most scholars think the Essenes seceded from the Zadokite priests. They saw themselves as the genuine remnant of Israel, upholding the true covenant with God, and attributed their interpretation of the Torah to their early leader, the Teacher of Righteousness, possibly a legitimate high priest. Embracing a conservative approach to Jewish law, they observed a strict hierarchy favoring priests (the Sons of Zadok) over laypeople, emphasized ritual purity, and held a dualistic worldview.
