1 Chronicles 6:31-48

Now these are those whom David appointed over the service of song in the house of the LORD after the ark [of the covenant] rested there. They ministered with singing before the tabernacle of the Tent of Meeting, until Solomon had built the LORD’S house (temple) in Jerusalem, performing their service in due order. These men and their sons served from the Kohathites: Heman the singer, the son of Joel, the son of Samuel [the great prophet and judge], the son of Elkanah [III], the son of Jeroham, the son of Eliel, the son of Toah, the son of Zuph, the son of Elkanah [II], the son of Mahath, the son of Amasai, the son of Elkanah [I], the son of Joel, the son of Azariah, the son of Zephaniah, the son of Tahath, the son of Assir, the son of Ebiasaph, the son of Korah, the son of Izhar, the son of Kohath, the son of Levi, the son of Israel (Jacob). Heman’s [tribal] brother Asaph stood at his right hand: Asaph the son of Berechiah, the son of Shimea, the son of Michael, the son of Baaseiah, the son of Malchijah, the son of Ethni, the son of Zerah, the son of Adaiah, the son of Ethan, the son of Zimmah, the son of Shimei, the son of Jahath, the son of Gershom, the son of Levi. Their relatives the sons of Merari stood at the left hand: Ethan the son of Kishi, the son of Abdi, the son of Malluch, the son of Hashabiah, the son of Amaziah, the son of Hilkiah, the son of Amzi, the son of Bani, the son of Shemer, the son of Mahli, the son of Mushi, the son of Merari, the son of Levi. Their relatives the Levites [who were not descended from Aaron] were appointed for all the other kinds of service of the tabernacle of the house of God.
