A harp for Saul

1 Samuel 16:15-16 - Saul's attendants said to him, "See, an evil spirit from God is tormenting you. Let our lord command his servants here to search for someone who can play the harp. He will play when the evil spirit from God comes upon you, and you will feel better."

I wonder what kind of torments Saul went through. What physical signs did he show that others knew he was being tormented? Was he in physical pain? Did he have hallucinations? Was he mentally disturbed? Did he shout or scream in anguish, anger, or pain?

I wonder how his servants knew it was an evil (or injurious) spirit from God. Was there a prophet among them who was told this was the case?

I wonder how they decided upon the harp as a remedy. Had they heard of it working in other similar cases? One servant seemed to have David in mind almost immediately. Had he been thinking of David earlier and thus suggested the harp remedy? Was he a friend of David who was looking to get him a better gig than shepherding?

David also became one of Saul's armor-bearers. I wonder how many armor-bearers Saul had and needed. Were all the armor-bearers referred to here Saul's personal armor-bearers, or did they serve the army in general? I wonder if being an armor-bearer was a difficult job.
