2 Chronicles 30
21 Ref And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised Jehovah day by day, `singing' with loud instruments unto Jehovah.
22 Ref And Hezekiah spake comfortably unto all the Levites that had good understanding `in the service' of Jehovah. So they did eat throughout the feast for the seven days, offering sacrifices of peace-offerings, and making confession to Jehovah, the God of their fathers.
23 Ref And the whole assembly took counsel to keep other seven days; and they kept `other' seven days with gladness.
