David told the leaders of the Levites to appoint their fellow Levites as musicians to make a joyful sound with musical instruments: lyres, harps and cymbals.
So the Levites appointed Heman son of Joel; from his relatives, Asaph son of Berekiah; and from their relatives the Merarites, Ethan son of Kushaiah;
and with them their relatives next in rank: Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-Edom and Jeiel, the gatekeepers.
The musicians Heman, Asaph and Ethan were to sound the bronze cymbals;
Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah and Benaiah were to play the lyres according to alamoth,
and Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, Jeiel and Azaziah were to play the harps, directing according to sheminith.
Kenaniah the head Levite was in charge of the singing; that was his responsibility because he was skillful at it.
Berekiah and Elkanah were to be doorkeepers for the ark.
Shebaniah, Joshaphat, Nethanel, Amasai, Zechariah, Benaiah and Eliezer the priests were to blow trumpets before the ark of God. Obed-Edom and Jehiah were also to be doorkeepers for the ark.
So David and the elders of Israel and the commanders of units of a thousand went to bring up the ark of the covenant of the LORD from the house of Obed-Edom, with rejoicing.
Because God had helped the Levites who were carrying the ark of the covenant of the LORD, seven bulls and seven rams were sacrificed.
