text: According to Jewish writers Josephus and Philo, the Essenes numbered around four thousand, and resided in various settlements throughout Judaea. Conversely, Roman writer Pliny the Elder positioned them somewhere above Ein Gedi, on the west side of the Dead Sea. Pliny relates in a few lines that the Essenes possess no money, had existed for thousands of generations, and that their priestly class ("contemplatives") did not marry. Josephus gave a detailed account of the Essenes in The Jewish War (), with a shorter description in Antiquities of the Jews () and The Life of Flavius Josephus (). Claiming firsthand knowledge, he lists the Essenoi as one of the three sects of Jewish philosophy alongside the Pharisees and Sadducees. He relates the same information concerning piety, celibacy; the absence of personal property and of money; the belief in communality; and commitment to a strict observance of Sabbath. He further adds that the Essenes ritually immersed in water every morning (a practice similar to the use of the mikveh for daily immersion found among some contemporary Hasidim), ate together after prayer, devoted themselves to charity and benevolence, forbade the expression of anger, studied the books of the elders, preserved secrets, and were very mindful of the names of the angels kept in their sacred writings.
  The Essenes have gained fame in modern times as a result of the discovery of an extensive group of religious documents known as the Dead Sea Scrolls, which are commonly believed to be the Essenes' library. The scrolls were found at Qumran, an archaeological site situated along the northwestern shore of the Dead Sea, believed to have been the dwelling place of an Essene community. These documents preserve multiple copies of parts of the Hebrew Bible along with deuterocanonical and sectarian manuscripts, including writings such as the Community Rule, the Damascus Document, and the War Scroll, which provide valuable insights into the communal life, ideology and theology of the Essenes.
