'Harp' in the Bible

After that thou shalt come to the hill of God, where is the garrison of the Philistines: and it shall come to pass, when thou art come thither to the city, that thou shalt meet a band of prophets coming down from the high place with a psaltery, and a timbrel, and a pipe, and a harp, before them; and they will be prophesying:

Let our lord now command thy servants, that are before thee, to seek out a man who is a skilful player on the 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: so Saul was refreshed, and was well, and the evil spirit departed from him.
