(i.e., assembler; Sept. 'Ασάβ), a Levite, son of Barachias, eminent as a musician, and appointed by David to preside over the sacred choral services which he organized. The "sons of Asaph" are afterwards mentioned as choristers of the temple, and this office appears to have been made hereditary in his family (1 Chron. xxv. 1, 2). The titles of twelve of the Psalms (lxxiii. to lxxxiii.) bear his name.
