Jubilee

In ancient Israel, a special regard for the lunar cycle may have been the very reason for why each 7th year was once specially tracked and celebrated. It is obvious that what we read in Leviticus is the lunar approach to the Jubilee. The 50th year was based on a 49 lunar week count which interfaced with the solar year. If anything were to disturb this orderly function of time cycles, then there would be chaos on this planet and all life would disappear. All of these systems allow for no error in the interpretation.
