2 Chronicles 30:21-23

MSB(i) 21 The Israelites who were present in Jerusalem celebrated the Feast of Unleavened Bread for seven days with great joy, and the Levites and priests praised the LORD day after day, accompanied by loud instruments of praise to the LORD. 22 And Hezekiah encouraged all the Levites who performed skillfully before the LORD. For seven days they ate their assigned portion, sacrificing fellowship offerings and giving thanks to the LORD, the God of their fathers. 23 The whole assembly agreed to observe seven more days, so they observed seven days with joy.
