“These are the men who served the temple and their sons. Of the sons of the Kohathites there was Heman the singer, son of Joel, son of Samuel, son of Elkanah, son of Jeroham, son of Eliel, son of Toah, son of Zuph, son of Elkanah, son of Mahath, son of Amasai, son of Elkanah, son of Joel, son of Azariah, son of Zephaniah, son of Tahath, son of Assir, son of Ebiasaph, son of Korah, son of Izhar, son of Kohath, son of Levi, son of Israel.”
This is really a passage about one person, Heman, the singer, who then traced his lineage right back to Israel in 22 generations, via (1) Levi, (2) Kohath, (3) Izhar, (4) Korah, (5) Ebiasaph, (6) Assir, (7) Tahath, (8) Zephaniah, (9) Azariah, (10) Joel, (11) Elkanah, (12) Amasai, (13) Mahath, (14) Elkanah, (15) Zuph, (16) Toah, (17) Eliel, (18) Jeroham, (19) Elkanah, (20) Samuel, (21) Joel and then himself (22) Heman. Heman is called a singer and not a musician. The names are pretty much the same as earlier in this chapter, but there are a few different names here compared to the earlier genealogy. Heman is clearly the grandson of the prophet Samuel via Joel. Instead of Eliab it is now Eliel which is the name of 9 different people in the biblical literature. Nahath has become Toah, but this is the only time that this name appears. Zophai has become Zuph, which is also a place. Mahath has been added since there is one other person beside this one. Amminadab has become Izhar. Uriel his son, Uzziah his son, and Shaul have been dropped. Otherwise it is the same.
