Bible Verses About Sling: Used in war

Among all this people there were seven hundred chosen men left-handed; everyone could sling stones at a hair-breadth, and not miss.

They beat down the cities; and on every good piece of land they cast every man his stone, and filled it; and they stopped all the springs of water, and felled all the good trees, until in Kir Hareseth only they left its stones; however the men armed with slings went about it, and struck it.

Uzziah prepared for them, even for all the army, shields, and spears, and helmets, and coats of mail, and bows, and stones for slinging.
