2 Chronicles 30:17-20

Since many people in the crowd had not made themselves holy, the Levites killed the Passover lambs for everyone who was not clean. The Levites made each lamb holy for the LORD. Although many people from Ephraim, Manasseh, Issachar, and Zebulun had not purified themselves for the feast, they ate the Passover even though it was against the law. So Hezekiah prayed for them, saying, “LORD, you are good. You are the LORD, the God of our ancestors. Please forgive all those who try to obey you even if they did not make themselves clean as the rules of the Temple command.” The LORD listened to Hezekiah’s prayer, and he healed the people.
