'Evil Spirit' in the Bible

Now the spirit of the Lord had gone from Saul, and an evil spirit from the Lord was troubling him.

And Saul's servants said to him, See now, an evil spirit from God is troubling you.

Now give orders to your servants who are here before you to go in search of a man who is an expert player on a corded instrument: and it will be that when the evil spirit from God is on you, he will make music for you on his instrument, and you will get well.

And whenever the evil spirit from God came on Saul, David took his instrument and made music: so new life came to Saul, and he got well, and the evil spirit went away from him.

Now on the day after, an evil spirit from God came on Saul with great force and he was acting like a prophet among the men of his house, while David was making music for him, as he did day by day: and Saul had his spear in his hand.

And an evil spirit from the Lord came on Saul, when he was seated in his house with his spear in his hand; and David made music for him.
