2 Chronicles 30:18-20

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.
