'Instruments' in the Bible
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: "Certainly he is good; certainly his loyal love endures!" Then a cloud filled the Lord's temple.
The priests stood in their assigned spots, along with the Levites who had the musical instruments used for praising the Lord. (These were the ones King David made for giving thanks to the Lord and which were used by David when he offered praise, saying, "Certainly his loyal love endures.") Opposite the Levites, the priests were blowing the trumpets, while all Israel stood there.
With the timber the king made steps for the Lord's temple and royal palace as well as stringed instruments for the musicians. No one had seen anything like them in the land of Judah prior to that.)
They entered Jerusalem to the sound of stringed instruments and trumpets and proceeded to the temple of the Lord.
Then she saw the king standing by his pillar at the entrance. The officers and trumpeters stood beside the king and all the people of the land were celebrating and blowing trumpets, and the musicians with various instruments were leading the celebration. Athaliah tore her clothes and yelled, "Treason! Treason!"
King Hezekiah stationed the Levites in the Lord's temple with cymbals and stringed instruments, just as David, Gad the king's prophet, and Nathan the prophet had ordered. (The Lord had actually given these orders through his prophets.)
The Levites had David's musical instruments and the priests had trumpets.
Hezekiah ordered the burnt sacrifice to be offered on the altar. As they began to offer the sacrifice, they also began to sing to the Lord, accompanied by the trumpets and the musical instruments of King David of Israel.
