2 Chronicles 30:18–20

For 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 who 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.” The LORD listened to Hezekiah, and healed the people.
