2 Chronicles 30:17-19

17Since many in the crowd had not consecrated themselves, the Levites had to kill the Passover lambs for all those who were not ceremonially clean and could not consecrate their lambs to the Lord. 18Although most of the many people who came from Ephraim, Manasseh, Issachar and Zebulun had not purified themselves, yet they ate the Passover, contrary to what was written. But Hezekiah prayed for them, saying, “May the Lord, who is good, pardon everyone 19who sets their heart on seeking God—the Lord, the God of their ancestors—even if they are not clean according to the rules of the sanctuary.”
