2 Chronicles 30:21-22, 25

So the people of Israel who were present in Jerusalem joyously celebrated the Festival of Unleavened Bread for seven days. Each day the Levites and priests sang to the LORD, accompanied by loud instruments. Hezekiah encouraged all the Levites regarding the skill they displayed as they served the LORD. The celebration continued for seven days. Peace offerings were sacrificed, and the people gave thanks to the LORD, the God of their ancestors.

The entire assembly of Judah rejoiced, including the priests, the Levites, all who came from the land of Israel, the foreigners who came to the festival, and all those who lived in Judah.
