'Rocks' in the Bible

He threw rocks at David and all of David's staff who were accompanying him, while all the rest of the entourage, including all of David's security detail, were close by him.

So David and his entourage went on their way, and Shimei walked along the hillside with him, cursing, throwing rocks, and tossing dirt at David as they went along.

Meanwhile, Joab's army grabbed Absalom's body, tossed it into a large pit in the forest, and filled it up with a huge pile of rocks. Then the Israelis ran away back to their homes.
