Ver. 33-38. And these are they that waited with their children,.... They and their posterity, who officiated in the service of singing psalms in the sanctuary: the three heads of them were of the three families of the Levites, as follow:
of the sons of the Kohathites, Heman a singer; the chief of the singers, and who composed psalms and hymns, which are in the book of Psalms:
the son of Joel, the son of Shemuel; or Samuel. This Heman was grandson of Samuel the prophet; for whose sake his genealogy is traced up to Jacob or Israel in the following verses, and stands thus; after Samuel, Elkanah, Jeroham, Eliel, Toah, Zuph, Elkanah, Mahath, Amasai, Elkanah, Joel, Azariah, Zephaniah, Tahath, Assir, Ebiasaph, Korah, Izhar, Kohath, Levi, Israel.
