2 Chronicles 30:21-23

Darby Translation

²¹ And the children of Israel, that were present at Jerusalem, held the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised Jehovah day by day, with the instruments of praise to Jehovah.

²² And Hezekiah spoke consolingly to all the Levites that had understanding in the good knowledge of Jehovah; and they ate the feast-offerings the seven days, sacrificing peace-offerings, and extolling Jehovah the God of their fathers.

²³ And the whole congregation took counsel to observe other seven days; and they observed the seven days with gladness.
