2 Chronicles 5:11-13

Then the priests left the Holy Place. All the priests who were present had purified themselves, whether or not they were on duty that day. And the Levites who were musicians—Asaph, Heman, Jeduthun, and all their sons and brothers—were dressed in fine linen robes and stood at the east side of the altar playing cymbals, lyres, and harps. They were joined by 120 priests who were playing trumpets. The trumpeters and singers performed together in unison to praise and give thanks to the LORD. Accompanied by trumpets, cymbals, and other instruments, they raised their voices and praised the LORD with these words: “He is good! His faithful love endures forever!” At that moment a thick cloud filled the Temple of the LORD.
