'Yelling' in the Bible

When King David got to Bahurim, a man belonging to the family of the house of Saul was just coming out. His name was Shimei son of Gera, and he was yelling curses as he approached.

So David and his men went on their way. But Shimei kept going along the side of the hill opposite him, yelling curses as he threw stones and dirt at them.
