According to the 1906 Jewish encyclopedia, The Letter of Aristeas states that creators of the Septuagint washed their hands in the sea each morning before prayer;[34] Josephus states that this custom was the reason for the traditional location of synagogues near water.[35] Biblical scholars regard this custom as an imitation by the laity of the behaviour of the priests.[3] A baraita offers, as justification for the ritual of hand-washing after waking, the belief that a spirit of impurity rests upon each person during the night, and will not leave until the person's hands are washed,[36] and the Zohar argues that body is open to demonic possession during sleep because the soul temporarily leaves the body during it;[17] the kabbalah argues that death awaits anyone who walks more than four yards from their bed without ablution.[17] According to [specify], the cup containing the water has to be able to carry a certain amount [specify] of water, and it should have two handles[citation needed].
