2 Chronicles 29:27 MSG

[27] Then Hezekiah gave the signal to begin: The Whole-Burnt-Offering was offered on the Altar; at the same time the sacred choir began singing, backed up by the trumpets and the David orchestra while the entire congregation worshiped. The singers sang and the trumpeters played all during the sacrifice of the Whole-Burnt-Offering. When the offering of the sacrifice was completed, the king and everyone there knelt to the ground and worshiped. Then Hezekiah the king and the leaders told the Levites to finish things off with anthems of praise to God using lyrics by David and Asaph the seer. They sang their praises with joy and reverence, kneeling in worship.
