David and all the Israelites were celebrating in the presence of the Lord. They were playing wooden instruments: lyres, harps, tambourines, rattles, and cymbals.
There was also a second group of Levites: Zechariah, Jaaziel, Shemiramoth, Jehiel, Unni, Eliab, Benaiah, Maaseiah, Mattithiah, Eliphelehu, Mikneiah, Obed-Edom, and Jeiel. They were the Levite guards.
