Asaph was one of the three Chief Musicians of worship for the Tribe of Levi during the reign of King David over Israel. Specifically Asaph was a cymbal player and led music related to the Ark of the Covenant; both in the Tabernacle and the First Temple. Asaph was also a seer, a prophet with the ability of foresight. Asaph wrote several psalms that were eventually included in the Book of Psalms.
