Jewish and Roman method of computing time.

다국어 초록 (Multilingual Abstract)

  Seven nights and days constitute a week; six of these were appropriated to labour and the ordinary purposes of life, and the seventh day, or sabbath, was appointed by God to be observed as a day of rest, because that on it he had rested from all his work, which God had created and made. This division of time was universally observed by the descendants of Noah; and being lost during the bondage of the Israelites in Egypt, was revived and enacted by Moses agreeably to the divine command.
