Sling used in War

Among all these soldiers there were 700 select left-handers, each of whom could sling a stone at a hair without missing.

They destroyed the cities, and each man threw stones on every good field until it was covered. They stopped up every spring and cut down every good tree. Only Kir-haraseth was left with stones in place, but men with slings surrounded it and attacked it as well.

Uzziah supplied the entire army with shields, spears, helmets, armor, bows, and slingstones.
