Harp

Watson's Biblical & Theological Dictionary

a stringed musical instrument. The Hebrew word kinaor, which is translated "harp" in our English version, very probably denoted all stringed instruments. By the Hebrew, the harp was called the pleasant harp; and it was employed by them, not only in their devotions, but also at their entertainments and pleasures. It is probable, that the harp was nearly the earliest, if not the earliest instrument of music. David danced when he played on the harp: the Levites did the same. Hence it appears, that it was light and portable, and that its size was restricted within limits which admitted of that service, and of that manner of using it.
