„The Sabbath is entirely independent of the month and unrelated to the moon. Its date is not determined by any event in nature, such as the new moon, but by the act of creation. Thus the essence of the Sabbath is completely detached from the world of space.
The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time. It is a day on which we are called upon to share in what is eternal in time, to turn from the results of creation to the mystery of creation; from the world of creation to the creation of the world.“Abraham Joshua Heschel
