All the Levites who were musicians, including Asaph, Heman, Jeduthun, and their sons and relatives, wore linen. They played cymbals and stringed instruments as they stood east of the altar. They were accompanied by 120 priests who blew trumpets.

The trumpeters and musicians played together, praising and giving thanks to the Lord. Accompanied by trumpets, cymbals, and other instruments, they loudly praised the Lord, singing: ¹  “Certainly he is good; certainly his loyal love endures!” Then a cloud filled the Lord’s temple. ² 

King Hezekiah ¹  stationed the Levites in the Lord’s temple with cymbals and stringed instruments, just as David, Gad the king’s prophet, ²  and Nathan the prophet had ordered. (The Lord had actually given these orders through his prophets.)
