Asaph is one of the Biblical names people do not recognize easily. He was a musician/composer and teacher appointed by King David to lead worship. He led worship on profound occasions including the return of the Ark of the Covenant to Jerusalem and perhaps the Temple Dedication Ceremony under King Solomon (at least his students were there). Read about him in 1st and 2nd Chronicles, and read about the students he left behind in Nehemiah. Twelve of the psalms are credited to Asaph (#50, #73-#83), meaning he may have written more of the Bible than Jonas, Jude, James or Peter.

Then on that day David first appointed the singing of praises to the LORD by Asaph and his kindred. "O give thanks to the LORD, call on his name, make known his deeds among the peoples." 1 Chronicles 15:7
