Slings (20:16) were weapons made of two long straps, usually either leather or cloth. These were attached to a wider pocket in the middle, where the thrower would place a rock or some other object. The sling was then swung above the head until one of the straps was let go, releasing the rock. Slings were designed to incapacitate the enemy. A fellow soldier with a sword or spear could then deliver the fatal blow.
