2 Chronicles 29:30 (KJV)

And all the congregation worshipped, and the singers sang, and the trumpeters sounded: and all this continued until the burnt offering was finished.

And when they had made an end of offering, the king and all that were present with him bowed themselves, and worshipped.

Moreover Hezekiah the king and the princes commanded the Levites to sing praise unto the Lord with the words of David, and of Asaph the seer. And they sang praises with gladness, and they bowed their heads and worshipped.

Then Hezekiah answered and said, Now ye have consecrated yourselves unto the Lord, come near and bring sacrifices and thank offerings into the house of the Lord. And the congregation brought in sacrifices and thank offerings; and as many as were of a free heart burnt offerings.

And the number of the burnt offerings, which the congregation brought, was threescore and ten bullocks, an hundred rams, and two hundred lambs: all these were for a burnt offering to the Lord.
