Easton's Bible Dictionary (1897)
(Heb. menatstseah), the precentor of the Levitical choir or orchestra in the temple, mentioned in the titles of fifty-five psalms, and in Hab. 3:19, Revised Version. The first who held this office was Jeduthun (1 Chr. 16:41), and the office appears to have been hereditary. Heman and Asaph were his two colleagues (2 Chr. 35:15).
