'Sling' in the Bible

And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag which he had, even in his wallet; and his sling was in his hand: and he drew near to the Philistine.

So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David.

And though men be risen up to pursue thee, and to seek thy soul, yet the soul of my lord shall be bound in the bundle of life with Jehovah thy God; and the souls of thine enemies, them shall he sling out, as from the hollow of a sling.
