“King David also commanded the chiefs of the Levites to appoint their kindred as the singers to play on musical instruments, on harps, lyres, and cymbals, to raise loud sounds of joy. So the Levites appointed Heman son of Joel with his kindred Asaph son of Berechiah. Of the sons of Merari and their kindred, was Ethan son of Kushaiah. With them were their kindred of the second order Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, and Mikneiah, and the gatekeepers Obed-edom and Jeiel. The singers, Heman, Asaph, and Ethan, were to sound bronze cymbals. Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah were to play harps according to Alamoth. But Mattithiah, Eliphelehu, Mikneiah, Obed-edom, Jeiel, and Azaziah were to lead with lyres according to the Sheminith. Chenaniah, leader of the Levites in music, should direct the music, for he understood it. Berechiah and Elkanah were to be gatekeepers for the ark. Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah, and Eliezer, the priests, should blow the trumpets before the ark of God. Obed-edom and Jehiah also were to be gatekeepers for the ark.”
Ever the musician King David, in fact, wanted some kind of band or orchestra to accompany the ark on its travels. He wanted the Levites to be in charge of music, to play the harp, the lyre, and the cymbals. The Kohathite Levite Heman, son of Joel and the grandson of the prophet Samuel, was appointed by King David as one of the leaders of the temple-singing earlier in chapter 6 of this book. Although Asaph the son of Berechiah is called Heman’s kindred he is actually a Gershonite Levite, not a Kohathite Levite, as in chapter 6 of this book. The 3rd leader was the Merarite Ethan, so that all three main braches of the Levites were included. There was a 2nd order of 11 singers or musicians. The 3 leaders were to play the cymbals. 8 people were to play the harps according to Alamoth, which means some kind of high pitch like a female voice. 6 people were to play the lyres according to Sheminith, which is a lower pitch or the lowest pitch of a male voice. Chenaniah was in charge of the music because he seemed to understand it better than anyone else. There were 7 horn blowers. This seems like it was very organized here, while in 2 Samuel, chapter 6, it seemed more haphazard. It looks like here there are about 24 people playing 4 different instruments, cymbals (3), harps (8), lyres (6), and trumpets (7). Obed-edom keeps showing up as a gate keeper, but actually the ark was at his house, since there is no indication that they are different people.
