2 Chronicles 30
After Hezekiah repaired the temple, he called the Israelites together to celebrate the Passover—something that hadn’t been done for a long, long time. It was a grand celebration—with music and feasting and thousands of sacrifices. The people were having such a great time that, at the end of the prescribed seven days, they decided to extend the celebration for another seven days. There was one slight problem, however: "Although 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 who 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.' And the Lord heard Hezekiah and healed the people." (vs 18-20)
