'Musicians' in the Bible
All the musicians who were descendants of Levi, including Asaph, Heman, Jeduthun, and their sons and relatives wore linen and played cymbals and stringed instruments as they stood east of the altar. Accompanied by 120 priests who played trumpets,
the trumpeters and musicians played in union, praising and giving thanks to the LORD. They praised the LORD loudly and sang, "He is good, and his gracious love is eternal," accompanied by the trumpets, cymbals, and other musical instruments.) As they did this, a cloud filled the Temple, that is, the LORD's Temple,
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.)
He met with the people and appointed musicians to play before the Lord and praise his majestic splendor. As they marched ahead of the warriors they said: "Give thanks to the Lord, for his loyal love endures."
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!"
The workmen did their duties faithfully with these foremen supervising them: Jahath and Obadiah, descendants of Levi who were Merari's sons, Zechariah and Meshullam, descendants of Kohath, and various descendants of Levi, who were skilled musicians.
The musicians, the descendants of Asaph, manned their posts, as prescribed by David, Asaph, Heman, and Jeduthun the king's prophet. The guards at the various gates did not need to leave their posts, for their fellow Levites made preparations for them.
