2 Chronicles 30:21-25

The sons of Israel present in Jerusalem celebrated the Feast of Unleavened Bread for seven days with great joy, and the Levites and the priests were praising the Lord day after day with loud instruments to the Lord.

Then Hezekiah spoke encouragingly to all the Levites who showed good insight in the things of the Lord. So they ate for the appointed seven days, sacrificing peace offerings and giving thanks to the Lord God of their fathers.

Then the whole assembly decided to celebrate the feast another seven days, so they celebrated the seven days with joy.

For Hezekiah king of Judah had contributed to the assembly a thousand bulls and seven thousand sheep, and the princes had contributed to the assembly a thousand bulls and ten thousand sheep; and a large number of priests consecrated themselves.

All the assembly of Judah rejoiced, with the priests and the Levites and all the assembly that came from Israel, both the strangers who came from the land of Israel and those living in Judah.
