'Evil Spirit From God' in the Bible

And Saul's servants said unto him, Behold now, an evil spirit from God troubleth thee.

Let our lord now command thy servants, which are before thee, to seek out a man, who is a cunning player on an harp: and it shall come to pass, when the evil spirit from God is upon thee, that he shall play with his hand, and thou shalt be well.

And it came to pass, when the evil spirit from God was upon Saul, that David took the harp, and played with his hand; and Saul was refreshed, and was well, and the evil spirit departed from him.

And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul's hand.
