'Sling' in the Bible

He took his staff in his hand and chose for himself five smooth stones from the brook and put them in the pouch in his shepherd's bag. He approached the Philistine with his sling in his hand.

David defeated the Philistine with a sling and a stone; he struck down the Philistine and killed him, and there was no sword in David's hand.

If anyone should arise to pursue you and seek your life, may the life of your majesty be bound up with the LORD your God in a bundle of the living, and may he sling out the lives of your enemies from the pocket of a sling.
