2 Chronicles 30:24 (KJV)

And Hezekiah spake comfortably unto all the Levites that taught the good knowledge of the Lord: and they did eat throughout the feast seven days, offering peace offerings, and making confession to the Lord God of their fathers.

And the whole assembly took counsel to keep other seven days: and they kept other seven days with gladness.

For Hezekiah king of Judah did give to the congregation a thousand bullocks and seven thousand sheep; and the princes gave to the congregation a thousand bullocks and ten thousand sheep: and a great number of priests sanctified themselves.

And all the congregation of Judah, with the priests and the Levites, and all the congregation that came out of Israel, and the strangers that came out of the land of Israel, and that dwelt in Judah, rejoiced.

So there was great joy in Jerusalem: for since the time of Solomon the son of David king of Israel there was not the like in Jerusalem.
