The spring of the waters - The spring intended is probably that now called Ain-es-Sultan, which is not much more than a mile from the site of the ancient town. It is described as a large and beautiful fountain of sweet and pleasant water. The springs issuing from the eastern base of the highlands of Judah and Benjamin are to this day generally brackish.
