'Instrument' in the Bible

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.
