A day’s journey was the distance ordinarily traveled in one day, commonly estimated at about twenty-five to thirty miles by camel or horseback. Biblical references use the expression as a practical measure of travel time.
Definition
A day’s journey is the distance ordinarily traveled in one day. In the East, travel by camel or horseback commonly covered about twenty-five or thirty miles in six to eight hours.
Biblical Usage
The expression is used as a practical measure of travel. The three days’ journey mentioned in Exodus is explained as a journey occupying three days in going and returning.
Historical Background
The estimate concerns ordinary eastern travel by camel or horseback and therefore describes distance through expected travel time rather than a fixed geographical measurement.
