1 Samuel 19:10

Saul sought to smite David with the javelin “How sad and shocking a scene was this! David labouring with all his study and skill to relieve Saul's anguish; and Saul, in the same instant, meditating his destruction! sitting sullen and determined, with his javelin in his hand, watching his opportunity, and waiting, perhaps, until the power of music had so far calmed his spirits as to render his hand steady. He then darted his spear at David with all his might, and with such force, that, he happily declining it, it pierced and stuck into the wall; and David fled.” Delaney. Saul's wrath and fury, on this occasion, made him entirely forget his oath. So dangerous it is to be possessed with such passions! It seems likely, from Saul's having a javelin in or near his hand, that it was usual for kings, in those days, to hold one in their hands, in the same manner as a sceptre in after-times, as a mark of royal authority.
