1550s, member of a Jewish sect (first recorded 2c. B.C.E.), from Latin, from Greek Essenoi, of disputed etymology, perhaps from Hebrew tzenum "the modest ones," or Hebrew hashaim "the silent ones." Klein suggests Syriac hasen, plural absolute state of hase "pious." Related: Essenes.
1. Q . Was this the orthodox Jewish Temple or the Essene Temple?
