2 Chronicles 30:20

18For a multitude of the people, even many of Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover other than the way it is written. For Hezekiah had prayed for them, saying, “May the good LORD pardon everyone

19who sets his heart to seek God, the LORD, the God of his fathers, even if they aren’t clean according to the purification of the sanctuary.”

20The LORD listened to Hezekiah, and healed the people.

21The children of Israel who were present at Jerusalem kept the feast of unleavened bread seven days with great gladness. The Levites and the priests praised the LORD day by day, singing with loud instruments to the LORD.

22Hezekiah spoke encouragingly to all the Levites who had good understanding in the service of the LORD. So they ate throughout the feast for the seven days, offering sacrifices of peace offerings and making confession to the LORD, the God of their fathers.
