The term "evil spirit" (רוח רעה) appears only occasionally in the Hebrew Bible, most prominently in the story of the life of King Saul (I Samuel 16:14-23; 18:10; 19:9). Tormented by evil spirits, King Saul seeks relief from David's music, setting in motion the rise of the House of David in the Kingdom of Israel. The other instance in the Hebrew Bible where "evil spirits" are mentioned is the Book of Judges (9:23). Also, in I Kings (22:22-23) the term "false spirit" (רוח שקר) is used to denote the same concept (parallel verses appear in II Chronicles 18:21-22). Similarly, another term, the "impure spirit" (רוח הטמאה), appears in the Book of Zechariah (13:2). And while additional verses in the Hebrew Bible may refer to spirits associated with evil or harm (e.g., the Satan in Job), the concept of the evil spirit (at least when this term is used) seems vague and ill-defined, especially if we consider how widely the keyword "spirit" (רוח) appears alone or with other, mostly positive, adjectives. For example, there is the "divine spirit" (רוח אלהים), the "living spirit" (רוח חיים), the "wise spirit" (רוח חכמה). In the context of King Saul, it seems the Hebrew term for spirit (רוח) could be translated as a "state of mind". This translation makes this matter far less otherworldly and more of practical concern.
An Evil Spirit Plagues King Saul

(14) Now the spirit of the LORD had departed from Saul, and an evil spirit from the LORD began to terrify him. (15) Saul’s courtiers said to him, “An evil spirit of God is terrifying you. (16) Let our lord give the order [and] the courtiers in attendance on you will look for someone who is skilled at playing the lyre; whenever the evil spirit of God comes over you, he will play it and you will feel better.” (17) So Saul said to his courtiers, “Find me someone who can play well and bring him to me.” (18) One of the attendants spoke up, “I have observed a son of Jesse the Bethlehemite who is skilled in music; he is a stalwart fellow and a warrior, sensible in speech, and handsome in appearance, and the LORD is with him.” (19) Whereupon Saul sent messengers to Jesse to say, “Send me your son David, who is with the flock.” (20) Jesse took an ass [laden with] bread, a skin of wine, and a kid, and sent them to Saul by his son David. (21) So David came to Saul and entered his service; [Saul] took a strong liking to him and made him one of his arms-bearers. (22) Saul sent word to Jesse, “Let David remain in my service, for I am pleased with him.” (23) Whenever the [evil] spirit of God came upon Saul, David would take the lyre and play it; Saul would find relief and feel better, and the evil spirit would leave him.

(5) David went out [with the troops], and he was successful in every mission on which Saul sent him, and Saul put him in command of all the soldiers; this pleased all the troops and Saul’s courtiers as well. (6) When the [troops] came home [and] David returned from killing the Philistine, the women of all the towns of Israel came out singing and dancing to greet King Saul with timbrels, shouting, and sistrums. (7) The women sang as they danced, and they chanted:Saul has slain his thousands;David, his tens of thousands! (8) Saul was much distressed and greatly vexed about the matter. For he said, “To David they have given tens of thousands, and to me they have given thousands. All that he lacks is the kingship!” (9) From that day on Saul kept a jealous eye on David. (10) The next day an evil spirit of God gripped Saul and he began to rave in the house, while David was playing [the lyre], as he did daily. Saul had a spear in his hand, (11) and Saul threw the spear, thinking to pin David to the wall. But David eluded him twice. (12) Saul was afraid of David, for the LORD was with him and had turned away from Saul.

(8) Fighting broke out again. David went out and fought the Philistines. He inflicted a great defeat upon them and they fled before him. (9) Then an evil spirit of the LORD came upon Saul while he was sitting in his house with his spear in his hand, and David was playing [the lyre]. (10) Saul tried to pin David to the wall with the spear, but he eluded Saul, so that he drove the spear into the wall. David fled and got away.That night (11) Saul sent messengers to David’s home to keep watch on him and to kill him in the morning. But David’s wife Michal told him, “Unless you run for your life tonight, you will be killed tomorrow.” (12) Michal let David down from the window and he escaped and fled.
