2 Chronicles 29:28-30

28The entire congregation prostrated themselves, while the singers sang and the trumpeters played. All this continued until the burnt offering was finished.

29Now at the completion of the burnt offering, the king and all who were present with him knelt down and worshiped.

30Moreover, King Hezekiah and the officials ordered the Levites to sing praises to Adonai with the words of David and of Asaph the seer. So they sang praises with gladness and bowed down and worshiped.
