1 Samuel 13:22

22So it came about on the day of battle that 13:22 Because the Israelite did not yet know how to work iron, their weapons were limited to the bow and arrow, and the sling. The sling was a formidable projectile weapon that had a small cradle or pouch between two lengths of cord. It was used not only in combat by ancient people, but also for hunting game.neither sword nor spear was found in the hands of any of the people who were with Saul and Jonathan; but Saul and Jonathan his son had them.
