2 Chronicles 5:11-14

Then the priests left the holy place. All the priests who were present had sanctified themselves, regardless of their divisions. All the levitical musicians—Asaph, Heman, Jeduthun, and their families and relatives—were dressed in fine linen and stood east of the altar with cymbals, harps, and zithers, along with one hundred twenty priests blowing trumpets. The trumpeters and singers joined together to praise and thank the LORD as one. Accompanied by trumpets, cymbals, and other musical instruments, they began to sing, praising the LORD: Yes, God is good! Yes, God’s faithful love lasts forever! Then a cloud filled the LORD’s temple. The priests were unable to carry out their duties on account of the cloud because the LORD’s glory filled God’s temple.
