I Chronicles 6:29

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.

Though Joseph and Judah shared between them the forfeited honours of the birthright, yet Levi was first of all the tribes, dignified and distinguished with an honour more valuable than either the precedency or the double portion, and that was the priesthood. That tribe God set apart for himself; it was Moses's tribe, and perhaps for his sake was thus favoured. Of that tribe we have an account in this chapter. I. Their pedigree, the first fathers of the tribe (Ch1 6:1-3), the line of the priests, from Aaron to the captivity (Ch1 6:4-15), and of some other of their families (Ch1 6:16-30). II. Their work, the work of the Levites (v. 31-48), of the priests (Ch1 6:49-53). III. The cities appointed them in the land of Canaan (v. 54-81).
