'Harp' in the Bible

"After that you shall come to the hill of God, where is the garrison of the Philistines: and it shall happen, when you have come there to the city, that you shall meet a band of prophets coming down from the high place with a psaltery, and a tambourine, and a pipe, and a harp, before them; and they will be prophesying:

Let our lord now command your servants who are before you, to seek out a man who is a skillful player on the harp. It shall happen, when the evil spirit from God is on you, that he shall play with his hand, and you shall be well."

It happened, when the [evil] spirit from God was on Saul, that David took the harp, and played with his hand: so Saul was refreshed, and was well, and the evil spirit departed from him.
