1 Samuel 16:13-17

Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the LORD came upon David from that day forward. So Samuel rose up, and went to Ramah.

But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him.

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 Saul said unto his servants, Provide me now a man that can play well, and bring him to me.
