2 Chronicles 30:17 TLB

[17] Since many of the people arriving from Ephraim, Manasseh, Issachar, and Zebulun were ceremonially impure because they had not undergone the purification rites, the Levites killed their Passover lambs for them, to sanctify them. Then King Hezekiah prayed for them, and they were permitted to eat the Passover anyway, even though this was contrary to God's rules. But Hezekiah said, "May the good Lord pardon everyone who determines to follow the Lord God of his fathers, even though he is not properly sanctified for the ceremony."
