A Sabbath Day’s walk is a measurement mentioned several times in the Bible. It’s distance is approximately 5/8 of a mile or 1 kilometer. The term came into use because of the legalistic additional laws of the Pharisees. While the Old Testament instructs us to do no work on the Sabbath, the Pharisees went a step further in defining what constituted as work. There were many rules concerning what did and did not constitute as work – following all of these rules was probably more work than just following the spirit of the law which was to encourage rest.
A Sabbath’s Day walk was the distance that a person was allowed to walk before it was considered work and thus a person would be considered guilty of breaking the Sabbath.
