2 Chronicles 5:12-13

12All the Levites who were musicians—Asaph, Heman, Jeduthun, their sons, and their relatives—were dressed in fine linen and stood east of the altar with cymbals, harps, and lyres. With the musicians were 120 priests blowing trumpets. When the priests left the holy place,

13the trumpeters and singers praised and thanked the Lord in unison. Accompanied by trumpets, cymbals, and other musical instruments, they sang in praise to the Lord: “He is good; his mercy endures forever.” Then the Lord’s temple was filled with a cloud.
