Five smooth stones— Bishop Patrick thinks that this should rather be rendered five cleft or rough stones; as he thinks such would have been most fit for his purpose. But smooth stones would have entered more easily into the forehead, would have less obstacles in passing through the air, and were much more proper to reach the mark, when thrown from a sling.
