The Levites had ¹  David’s musical instruments and the priests had trumpets.

They swore their allegiance to the Lord, shouting their approval loudly and sounding trumpets and horns. ¹ 

They entered Jerusalem to the sound of stringed instruments and trumpets and proceeded to the temple of the Lord.

The men of Judah turned around and realized they were being attacked from the front and the rear. ¹  So they cried out for help to the Lord. The priests blew their trumpets,

The entire assembly worshiped, as the singers sang and the trumpeters played. They continued until the burnt sacrifice was completed.

Then she saw ¹  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!” ² 

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.

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 

Now look, God is with us as our leader. His priests are ready to blow the trumpets to signal the attack against you. ¹  You Israelites, don’t fight against the Lord God of your ancestors, ²  for you will not win!”
