2 Chronicles 29:28-30

28So all the assembly worshiped, the singers sang, and the trumpeters sounded; all this continued until the burnt offering was finished.

29And when they had finished offering, the king and all who were present with him bowed and worshiped.

30Moreover King Hezekiah and the leaders commanded the Levites to sing praise to the Lord with the words of David and of Asaph the seer. So they sang praises with gladness, and they bowed their heads and worshiped.
